Carla sighed as she watched her little boy dash into the room of his elder brother, crying.

Eren (experiment, first person)

I slammed the door behind myself as I entered nii-chan's room. I slid down the door until I was sitting on the floor. Tears were running down from my eyes, desperate sobs escaping my lips. Why did mom have to say all that? It's not true. It can't be true. That woman can't be the one nii-chan loves the most. I mean, nii-chan would never lie to me. He would never do something like that. My chest felt weird. It hurt, it burned, it felt like something in there was falling apart. I just want this feeling to stop. I want to see nii-chan. I want him to hold me like he did whenever I was upset. I want to him to tell me it's a lie. I still remember what nii-chan told me.

(experiment done)

Flashback (One year ago)

Eren opened his eyes and he was lost as he looked around himself not recognizing the place. It was some kind of forest. It wasn't like anything else he seen so far. It was the trees, they were abnormally big. He didn't know where he was, really but it felt familiar, so familiar. Like, like he's been here already. Long, long time ago. But how was that possible? He was only a five year old boy. When that thought crossed his mind he noticed something was different, something about himself. He was taller, lot taller than he should be and also his hands, they were much bigger than he remembers. His voice as well. Did he grow up? But how was that possible, until yesterday he was only a little boy. Or was he? Yesterday? He couldn't remember. What did he do yesterday? He could only remember his name. Eren. And one more, one more name, it was there, he couldn't have forgotten that name. Levi… Levi! He had to find him. He didn't know where he was or why he needed to find him but he knew that he had. He felt something, something bad was about to happen. He could only run through the forest calling out to his brother's name. Running and screaming until there was almost no air left in his lungs. That when he heard it, footsteps. Too loud to be something human. Bad feeling washed over him again, telling him to run. But he couldn't. He was frozen, paralyzed with fear. Even if he ran he wouldn't be able to escape. Thing was approaching too quickly. Footsteps got louder and louder. And then, he saw it. It was about ten meters tall. It's mouth were covered in blood and it had terrifying expression on its face, almost as it was insane. His eyes widened and his mouth trembled. He won't be able to escape. That thing, it's gonna…

"EREN RUN!" he heard familiar voice calling out to him. His voice. Levi's voice. It came from above. Just when he looked up Levi dashed towards the creature as if he was flying. It happened in split second. It swiftly caught Levi and stuffed him in its mouth. Complete terror overcame Eren as he saw droplets of Levi's blood dancing around like cherry blossoms in spring. His eyes widening, filling with tears. He fell on his knees, slowly turning into crying mess as his voice allowed him to scream…

"HEICHOU!"

Eren woke up in the middle of the night, screaming. He was panting, covered in cold sweat. His eyes wide, his little body shook like a leaf in the wind. He quickly got out of his bed and ran towards his brother's room. He opened the door screaming

"NII-CHAN!"

His brother opened his eyes and rubbed them to chase away the sleep. He looked at the trembling form of his little brother who was standing in front of him, a crying mess. He smiled sweetly as he extended his hands whispering in soothing voice.

"Eren, come here"

Eren ran into the strong arms of his elder brother wrapping his arms around Levi's neck, clinging onto him for dear life. He felt gentle had of his brother stroking his hair, placing one light kiss on top of his head.

"Did you have a nightmare?" he whispered softly. Eren just lightly nodded his head, refusing to let go of Levi yet. Levi laid down on the bed pulling Eren along so the smaller boy had his head resting against Levi's chest.

"Want to tell me what was it about?" he whispered, still stroking little boy's hair. After being held by his brother for couple of minutes Eren finally calmed down and started talking, quiet sobs still escaping his lips here and there.

"I was in a forest. Really big one with huge trees." He started quietly, remembering terrifying nightmare.

"It's okay, take your time" Levi whispered soothingly, still stroking hair of his little brother.

"And, I wasn't small anymore. I was big boy, just like nii-chan."

"Eh? You were big boy? That doesn't sound like such bad thing to me." Levi chuckled.

"Nii-chan!" Eren whined.

"Sorry, sorry. Continue."

"And I couldn't remember anything, only my name and you nii-chan. And I had this feeling that I had to find you right away or something bad will happen. And then I ran through the forest, looking for you. " Eren's words got more quiet as he got further away with the story.

"It's okay Eren. You know you can tell nii-chan." Levi whispered as he placed another kiss on top of Eren's head as a way of encouraging him to continue.

Eren took a deep breath before he started talking again. "A-and then I heard loud noises, like footsteps. And I got really scared and couldn't run so I just stood where I was" Tears started welling up again as he replayed the nightmare in his head once again. Levi squeezed him harder to his chest, encouraging him to finish the story.

"Footsteps kept getting louder and louder and then I saw this huge creature. About ten meters tall and it was really scary and fast. It wasn't wearing any clothes and it had really creepy expression on its face. And then nii-chan came. You called my name, telling me to run. I looked up and you were there, above me. You were really fast and you looked like you were flying, it was really cool. Bu-but that t-thing…" Eren was trembling once again, tears streaming down his face, clutching on Levi's shirt desperately.

"Shhh, It's okay Eren. It was just a dream. None of that was real. Just a bad dream. Come on, you can do it. You'll feel better. Trust your nii-chan, okay?" Levi placed his and under Eren's chin so he was looking up at him. He smiled reassuring smile to convince Eren that it will be alright.

"I-it grabbed you. A-and t-then. I-it a-ate you. And there w-was blood everywhere. A-and I started crying and I called out to you. I used this weird name. Heichou. A-and then I woke up" by the time he finished Eren was a crying mess once again. Trembling and sobbing in Levi's arms. Levi stroked his hair gently and whispered soothing words into his ear, placing a kiss here and there until Eren calmed down once again.

"Feeling better?" Levi asked once Eren's sobs and sniffles stopped.

"Y-yes" whispered little boy.

"Good" said Levi as he kissed his forehead.

"Nii-chan?"

"Hm?

"You'll always be there for me like this. Right?" boy whispered looking up at his brother's smiling face.

"Of course Eren. No matter what, nii-chan will always be there for you. I want you to remember that you are my most important person. Nii-chan loves you the most, forever. Don't forget that okay?"

"Okay" Eren murmured as sleep took him once again. No nightmares this time, because now he felt safe. Held by these strong arms, forever.

End of flashback

Even though he was half asleep, Eren still remembered these words clearly. It was a promise. A promise that bound two of them. Just like Levi said, forever. For all eternity.

Xxx

It's been a week since Levi left the house. Eren was once again in his brother's room, crying. Just this time he wasn't on the floor. He was on his brother's bed. Inhaling his scent that, even though faint, was still on the sheets.

Those dreams came again. They tortured him, haunted him. It wasn't always the same dream, but every single one was a nightmare. Eren feared going to sleep. He didn't know why but he felt like he couldn't tell his parents, like they wouldn't understand. If only Levi was still here. It's been only two days but Eren missed him so much. He missed sweet smiles, he missed those kind gray eyes. He missed being held by those strong arms every time he woke up in the middle of the night. He missed light kisses Levi would place on his head or cheek without any particular reason. He just missed Levi. Why did he have to leave? He promised he will always be there for him so why? Did he forget about their promise? Did it mean so little to him? Or was it because of her? Because of that woman. More tears formed in Eren's eyes as he remembered his mother's speech from two days ago. About that woman being Levi's most loved one. Eren felt so lonely, so lost, so betrayed. He clutched the sheets as more tears came. Since Levi left it's as if some kind of ocean formed in Eren's eyes. Tears just flowed out of his eyes, they just wouldn't stop. He laid there and cried when he felt sleep slowly overtaking him. He was afraid to fall asleep. He was afraid of those dreams. But his body wouldn't listen so his eyes slowly closed, sleep taking him away.

Eren opened his eyes to find himself in that place again. That world would be better expression. From all the dreams he had so far he learned couple of things. In this world he wasn't only little boy. He was 15. Also he learned that he was a soldier in the army that fought against those atrocious creatures, titans, was how they called them.

Eren was currently lying under a tree, resting so he assumed he was inside of walls. These dreams haven't felt like dreams anymore. The more time passed they felt like… Memories. Like he actually lived through all this. Long, long time ago.

"-ren, Eren!" familiar voice pulled him out of his thoughts. The one he loved to hear the most. His voice.

"Levi?"Eren answered looking up at object of his affection. Looking up only because he was lying down. Levi was kinda way shorter than him in here.

"Slacking off again, huh?" Levi flicked his forehead once as he said this.

"Ouch! What was that for?"Eren whined.

"That was for slacking when you should be working."Levi explained sitting next to him.

"I wasn't slacking, just resting."Eren pouted. Levi chuckled as he turned head to look at him.

"What?" asked Eren .

"You're just so adorable when you're sulking" Levi teased. And before Eren could say anything to complain Levi's mouth were on his, planting a sweet, loving kiss. It felt like heaven, having Levi so close. Without thinking Eren just leaned in started kissing back. It just felt so right, so natural.

"Oh? You're so needy today Eren" Levi whispered into his ear after pulling away just a bit. Levi nibbled on his ear and kept placing hot kisses down Eren's neck and jaw line…

"AH! " Eren shouted as he woke up from very strange dream he had just now. Sure, it wasn't a nightmare but… What was that anyway? What was Levi doing to him? In the dream it felt so pleasant, so nice but now only thing Eren felt was embarrassment. He felt his cheeks getting warmer as he thought how brothers shouldn't be doing something like that.

"Eren, Lunch! Come down here!" he heard his mom calling him. Eren took a deep breath and decided to try to forget about this dream for now. It might be harder than he thought though.

Xxx

Two weeks. That much time has passed since Levi left the house. Eren once again sat locked up in his brother's room, in his brother's bed. He really missed him now. He missed him so much it started to hurt. Levi called couple of times and asked to talk to Eren but Eren didn't want to. He just couldn't talk to him. He thought that if he heard Levi's voice he would break. Eren's cheeks flushed as he remembered that dream he had a week ago. Since that time nightmares stopped. But even though nightmares stopped Eren had those weird dreams every night. Every morning he would wake up extremely embarrassed with this feeling that whatever they were doing in that dream is not something brothers should do.

Eren groaned as he put his face into his hands. He felt something wet on them. Eh? Since when was he crying? All of a sudden he felt everything crush on him. All those dreams, the good and the bad, how much he missed Levi, how much he wanted to talk to him. And so he burst into tears. Shaking, sobbing, again. This has been happening every day in these two weeks, it was starting to get hard for Eren. He didn't want to cry anymore, he promised Levi he won't after all. And every single day single day for these two weeks he's been breaking that promise.

He heard faint knock on the door and he whispered trying to sound as normal as possible, assuming that his mother was the one knocking

"Mom, I'm not hungry. Can you leave me alone?"

Couple of seconds passed and he heard it. Levi's voice. After two weeks he…

"Eren, open the door. It's me"

Eren hands started shaking as he reached for the key to unlock the door. Was he ready for this? Could he really face Levi now? His hander lingered above door handle for a bit. He slowly opened the door and poked his head out.

"Nii-chan?"

"Yo" Levi said as lowered himself and wrapped his arms around Eren.

"Nii-chan!" Eren shouted throwing his arms around Levi's neck. Eren felt Levi lifting him up. He still cried, silently. After two weeks he finally got see his precious nii-chan. Eren still cried, but he felt so calm, so peaceful. Embraced by those strong arms. Levi caressed his hair, whispered softly into his ear, Eren was just so happy. They stood like that for a while until Eren calmed down. Levi put him down as he asked

"Calmed down now?"

Eren nodded as he wiped his eyes with the back of his hand. Then he remembered something. He maybe did break a promise but nii-chan did too! They were even now.

"Nii-chan, you lied to me!" he shouted.

"I know Eren, I should have come sooner. I'm sorry." Levi said after taking a deep breath. Since he apologized nicely Eren decided to forgive him. He couldn't really act all proud after all. Thinking back to all those tears.

"Okay, I will forgive you but you can never lie to me again!" Eren pouted attempting to look cute. Levi laughed. Mission accomplished.

"Nii-chan, don't laugh!"Eren shouted, attempting to attack his brother with another wave of cuteness.

"I'm sorry, I'm sorry" Levi said calming down his laugh. "I won't lie to you again" Levi said as held out his pinky to Eren. Eren hesitated for a moment but locked his finger with Levi's in the end asking

"Promise?"

"Promise." Levi smiled softly.

"Let's go now, mom is waiting." Levi said as he took Eren's hand

Eren nodded, huge grin spread across his face. He was so happy. Finally holding that hand, once again.

Xxx

As they entered living room Eren saw something he really didn't like, sitting on the couch. Or someone, it doesn't matter. He saw that woman, Petra. He had to calm down, he promised to his mom that day that he will make Levi proud and to stay calm was the only way to do it. He approached her slowly, stood in from of her, bowed and said

"I'm sorry Petra-san. I hope we can be friends."

"Awww, that is so sweet of you Eren. Of course we can be friends!" Petra tapped her lap as a sign for him to sit as huge smile spread across her face. Eren just tilted his head to the side in confusion.

"Come here!" she said as she pulled him up into her lap.

"So, will you tell me why didn't you like me before?" Eren froze. He couldn't tell her the real reason. Or could he?

"W-well it's just that before nii-chan was always playing with me and he was spending lot of time with me but when Petra-san came he was with you all the time and I thought nii-chan doesn't love me anymore a-and I thought it was your fault" Eren pouted in the cutest way he knew as he was saying all this. Expression Petra had on her face was quite unexplainable. It looked like her face was gonna melt. Like she just saw a baby panda cuddling with a puppy.

"Awww Eren you are so cute I could just eat you up!" she said as she squeezed the little boy in her lap like a teddy bear.

"And don't worry sweetie, I'm sure Levi still loves you very very much. I mean, who couldn't love you when you're so adorable!" Petra squeezed him even harder placing a kiss on his cheek. Eren just looked at woman and smiled in the most adorable way he could.

"Does anyone want some cake? I made a chocolate one to cheer Eren up but now that you're all here, we can share right?" Eren heard his mom speak.

"Yaaay , cake!" Eren shouted as he jumped out of Petra's lap and rushed to hug his mom. He wrapped his hands around her neck as he felt she was lifting it up. He gave her a loud smooch on the cheek. Eren heard his mom chuckle as she put him back down.

"Okay, okay. I'll be back in about five minutes. Don't break anything while I'm gone."Eren heard his mom say as she disappeared into the kitchen.

Eren turned around to go back to his mission, getting Petra to like him. But then he saw his nii-chan on the couch next to her. He looked awfully sad and frustrated. Eren's little ached just looking at Levi. He wanted to help him, to make him smile again, but how? Eren remembered that when he was sad or felt bad Levi would always hug him tightly and hold him until he calmed down. Eren moved slowly as he placed his legs over his brother's lap and wrapped his arms around his neck.

"Eren what-" he heard his brother speak but quickly shut his mouth as he returned the hug. Eren felt it again, those strong arms wrapping around him and holding him in place like chains would. He had this feeling for a while, feeling that he won't be able to escape these chains, ever. His little arms maybe weren't as strong as Levi's and he might not even make him feel better by doing this but he still had to try. Try to bring that smile back on his beloved brother's face. One loud "awww" coming from Petra's direction snapped Eren out of his thoughts. Both brothers pulled away as they saw Petra staring at her phone with the sweetest smile ever. Eren wondered did woman lose her mind for a moment.

"Petra what-" he heard his brother say without finishing the sentence because Petra shoved her phone into his face.

"This is gonna be my new wallpaper" she almost sand, excitedly.

Eren and Levi both leaned in to look at the phone to see that Petra has captured this tender moment they just shared on her phone. Eren blushed as he looked at the picture remembering those dreams he had for the past week. He jumped out of Levi's lap and ran towards the kitchen, embarrassed. Eren rushed into the kitchen, completely red, panting.

"Eren honey what's wrong?"asked his mom.

"E-eh?" he looked at her, surprised. How could he forget that she was in there?

"No-nothing mom, don't worry" he said.

"Are you sure, you're all flushed, do you have a fever?" said his mom as she placed one hand on his forehead, her voice laced with concern.

"No mom! I d-don't have a fever! Everything's fine." He said as he laughed awkwardly.

"Okay. If you say so." said his mom turning back to that chocolate cake.

Xxx

After spending whole day together it was time for Levi and Petra to leave. Thus Eren found himself standing beside his mother in front of the door of their house, saying goodbye to his beloved nii-chan. Eren really didn't want Levi to leave. It's true that they spent whole day together bit it still wasn't enough for Eren. He wanted to be with Levi just a little more. He wanted to fall asleep in his embrace just once more. But even if he asked to go with them, their mom probably wouldn't allow it. Eren was very fidgety at times like this. When he wanted something really badly but was equally afraid to ask for that something.

"Eren, what is it?" his brother's voice snapped him out of his thoughts.

"W-what?" Eren stuttered, confused. Did he say some of that bout loud? Did he do something?

"You can't fool me Eren. Whenever you're fidgety like that, it means you want something but you're scared to ask. What is it?"

'How did he know?!' Eren knew his brother could read him very well since they spent all their time together, but this?!

"W-well, it's just that I r-really missed nii-chan. A-and I wanted to a-ask can I sleep over at nii-chan's house tonight?" Eren shut his eyes tightly as he stuttered. He felt massive amount of fear wash over him. Why was he so scared? Why was he shaking so much?

"Eren, I'm sure nii-chan is pretty busy over there and he-"

"No, it's okay." Eren slowly opened his eyes as he heard Levi interrupting their mother's sentence. "It's Sunday tomorrow, I have no classes and I really missed him too. I want him to come over."

At hearing those words Eren's heart fluttered and a huge smile spread across his face. All that fear completely disappearing and being replaced with happiness. Eren rushed into the house and towards his room to get ready. He was so excited, it felt his heart is about to leave his chest any second now. His stomach fluttered like it was full of butterflies. He was going to spend night at his nii-chan's house!

Xxx

After about ten minutes Eren was ready and out the door. He had his little back pack and in it his pajamas, his tooth brush, that weird, ugly toy Hanji gave him when he was two years old. For some reason he was very attached to that toy, he couldn't sleep without it, even though that toy looked a lot like one of those things from his dreams, titans.

He sat looked outside the window from the back seat of Levi's car. He was a bit mad because he got to sit in the back and Petra got the front. Whenever they stopped talking there would be this comfortable silence in the car. Petra seemed to not like silence since she was always breaking it. Eren didn't particularly enjoy those stories she was telling him. Those were things for big kids, Eren didn't understand that. But he still listened, he listened because she talked a lot about Levi in those stories and he loved listening about his nii-chan the most.

They were driving for some time when they stopped in front of building Petra lived in. Eren felt huge amount of anger and frustration as he saw her kissing her brother before she left the car. Why? Why can she kiss nii-chan like that and I can't ?! As soon as he saw she turned her back to them Eren sticked his tongue out to her. He wished she would just disappear, it's her fault he cried so much for the past few weeks anyway. In those dreams he had nii-chan kissed him like that. It wasn't fear… Eren's train of thoughts was interrupted when he heard his brother chuckle.

"I saw that you know?"

Eren blushed and turned his head away at his brother's words. Car was filled with silence once more as his brother continued driving to his place.

Xxx

Eren was sitting on the couch in his brother's apartment as he waited for him to bring something to drink from the kitchen. He was supposed to be happy. He finally got a chance to spend a night with Levi but he just couldn't stop thinking about that kiss he shared with Petra. He still wanted Levi to kiss him that way.

"What was that for?" Eren turned around as he heard his brother's voice. He walked in the room with cup of hot cocoa for Eren.

"What?" Eren asked as he took the drink with both of his little hands and blew into it so he doesn't burn himself.

"That thing you did when Petra left the car, I thought you two were finally getting along." He heard his brother say. He was already tired of lying and saying that everything was okay. He decided to just tell his brother the truth.

"I was being nice to her just because mom told me to."

"Mom told you to?" Levi asked. Eren heart ached as remembered conversation he had with their mom after Levi left. He was afraid to say it. He was afraid of Levi's reaction. Will he get angry? Will he laugh at him? Whatever happens there's no turning back now. Eren took s deep breath as he started speaking

"After you left that day I talked to mom and she told me that I should get along with Petra because she is someone nii-chan loves the most and that I'm hurting Petra when I'm being mean to her and that nii-chan is also hurt when Petra is…" Eren broke. Tears started streaming down his face as he talked. He couldn't even bear to think about that let alone say it out loud. He was shaking like a leaf in the wind. He was breaking inside, Levi's silence was breaking him. "Say something already!" he thought. He gasped when he felt Levi's hands wrapping around him. Eren threw his arms around Levi's neck clinging for dear life, sobbing into his neck. He felt Levi pulling away slightly, cupping his cheek. Eren's tears still falling, one after another. He felt Levi's lips on his cheeks, catching every single tear. Kissing them away. It felt like heaven, like one those dreams he had over the past week. Eren just hoped that this wasn't a dream, he hoped this was reality, and he hoped it never ends. Eren felt like he was losing himself as Levi kept kissing him. Like the other Eren was taking over, the one he was in his dreams. Eren's tears slowly faded away, it was like he knew something now, something he didn't know before. Like his other self was talking to him, saying that it's okay. As Eren's tears completely faded away he looked up at Levi, smiling. His eyes still red and puffy from crying.

"Eren listen…" he heard his brother say.

"It's okay nii-chan, I know now" Eren said, smiling at his brother. It was more like the other Eren spoke, the older one. He saw Levi's face, smiling back at him.

"It's late. We should go to sleep" said Levi as he took Eren's little hand, leading him into the bedroom.

Xxx

Eren laid in bed, wide awake, his back facing Levi. He turned around to see Levi's sleeping face. He was slowly coming back, he should just wait for his body to grow up little bit more and he'll be able to come back completely. He took one more glance at Levi, noticed his chest rising up and down calmly. He seemed to be asleep. Eren leaned in, placing a soft, sweet kiss on Levi's lips.

"No matter what I'll always love you the most. Heichou…"

A|N (And that would be chapter number 6. Hope you enjoyed.

So much drama, so much tears, so much dreams, Eren's ghost… And for you perverts out there Eren wasn't about to have a dirty dream, even I am not that sick. That was a memory.

Well I hope you liked that chapter and that I moved your heart at least a little bit. Thanks for all the love and nice reviews I have been getting because those are the things that make me move my lazy ass and write more. Thank you all for reading.
