Author's Note: Okay so I've decided since I ended Red String of Fate, I wanna write OVA stories for it. This OVA story is gonna explore deeper into the High School Arc, which didn't last very long in the fanfic. I'm looking forward to writing this a lot!

It was early in the morning, but the sun shined in through the window. The entire bedroom was lit up from it. Eren Jaeger lay on his bed, sprawled out.

His entire bed was littered with chip crumbs, and even an Xbox controller. There was even some soda cans on his floor, as he drooled in his sleep.

He was 15 years old, and today was the first day was high school. The bedroom door opened, as Mikasa stepped in.

She was already dressed in her school uniform, her short black hair brushed neatly. She wore her red scarf, blinking.

"Oh Eren", she sighed, seeing his room. She frowned, but she picked up the soda cans, tossing them in the small trashcan. She then brushed the crumbs off of his bed, into the trash can, and set his controller on his desk.

She then knelt down at his bedside, and poked his face.

"Eren", she said softly. Color reached her cheeks, as she watched him sleep. She smiled softly. Eren's family took Mikasa in when they were 10 years old...five years ago.

After her parents were murdered, Mikasa latched onto Eren. The two however, were not legally adopted siblings.

Because they never saw each other as siblings. As children they had a crush on each other. Despite five years passing...Mikasa still had deep feelings for Eren.

But she wasn't sure if he felt the same way still.

"Eren!", she raised her voice a bit. Eren stirred, he groaned tiredly, his green eyes opening.

"Mikasa...?", he asked, out of it. He yawned, as he sat up stretching. "Eren, it's morning", Mikasa said.

"So..?", Eren asked, still half asleep. He blinked, his eyes watering as he looked at her.

"Why are you in your uniform?", he asked. Mikasa frowned.

"Eren, we have high school", she said. Eren starred at her blankly, and then it clicked.

"Oh CRAP!", he jumped out of bed, hurrying to his closet for his uniform.

After he was dressed, the two hurried downstairs.

"Damn it, we're gonna be late!", Eren complained, as he ran into the kitchen.

"You both still have a few minutes, eat your breakfast Eren", Carla said, as she brought food over to the table.

"Mikasa, aren't you hungry?", Eren asked, as he wolfed down his breakfast. "I ate an hour ago", Mikasa replied simply.

"What time did you wake up?!", Eren gawked at her.

"I woke up at 5, since I went to bed at a decent hour", replied Mikasa. Eren frowned.

"I went to bed at a decent hour too", he mumbled. "You didn't go to bed until 2 AM", Mikasa pointed out.

Eren sweat dropped, as he continued to eat his food fast.

"Eren, slow down! You'll choke!", Mikasa cried, worriedly. "No time to slow down! We're gonna be late!", Eren ate fast, as he drank his orange juice quickly.

After he finished, the two ran out. "Bye mom!", Eren yelled, running out. "We'll be back by 3", Mikasa added.

"Have a good day!", Carla called out, smiling.

Eren and Mikasa bolted down the street, heading for school.

"Give me a break! Why does high school have to start so early?!", Eren complained as he ran. Mikasa ran behind him.

She blinked then, seeing they were running under Sakura Trees.

"Eren, stop!", she cried then. "What?!", Eren asked, skidding to a stop, panting. "The first Sakura petals...they're in full bloom", Mikasa stated.

Eren blinked, but then he realized. He even felt his heart sink.

"You're right..", he gave a small, walking up to her. "They're up kind of high this year though...", he added.

"Give me a boost", Mikasa requested.

Eren nodded, he lifted her up on his shoulders, but his entire figure shook as he did. She really was heavy since she worked out a lot.

"Mikasa...hurry up!", Eren groaned struggling, his legs shaking. "Hold still!", Mikasa hissed, as she gently picked a couple.

"I'm trying!", Eren shook. "Okay", Mikasa gave him the clear, as he set her down. Eren staggered, panting.

"Did you get enough?", he asked worriedly. "Yes...", Mikasa smiled, as she placed them carefully in her bag.

Every Spring, when the Sakura Blossoms were in full bloom, Mikasa picked several to put on her parents graves in the cemetery.

Which is why Eren slowed his rush...he knew how much Mikasa still grieved for them. When they were children, Mikasa was so traumatized from witnessing it, she clung to Eren constantly, and had nightmares all the time.

As a teenager, she had grown more independent and strong, but she still thought about her parents at times.

"Let's get to school", Mikasa gave a small smile. "Oh, right!", Eren took Mikasa's hand, as they ran to the school.

Mikasa blushed a bit at Eren taking her hand. They saw Armin up ahead.

"Hey Armin!", Eren waved. "Hey guys!", Armin ran with them. "Mikasa, did you get your Sakura petals?", Armin asked.

Mikasa nodded. "I did", she smiled.

They hurried, and finally made it to the school. "Finally!", Eren panted as they stood at the entrance. The high school was huge.

It had a stone path courtyard, with a large fountain in the middle, and plenty of Sakura Trees. There was a Outdoor, in ground Olympic size swimming pool, a large gym, a whole yard for sports, a library, infirmary, dozens of classrooms, and a cafeteria.

There was also club rooms for P.E, Art, Music, Drama, Cooking, Writing, Reading, Anime, and Photography.

"Which class are we in?", Armin asked. "We're in Class 1-8...we're on the second floor", Mikasa replied.

"Let's hurry!", Eren ran ahead. Mikasa and Armin followed, as they hurried inside.

After they found their lockers, they hurried up to the second floor. "We actually made it!", Eren said relieved, seeing the time.

They entered the classroom, to see other students coming in as well.

"Okay students, we're gonna do a name call as soon as you take your seats", their female teacher said, as began finding a seat.

Eren sat down in the middle of the room, Armin beside him. A boy called Connie went to sit by Eren, and he suddenly felt Mikasa grip his arm so tightly, it went numb.

Connie froze, terrified, as Mikasa gave him the darkest death glare.

"This seat is taken", she growled, dangerously. "Y-Yes, ma'am! Sorry!", Connie quickly ran to the back of the class, as Mikasa sat down beside Eren.

"You know...you could have just kindly explained...", Eren chuckled.

Mikasa suddenly moved her desk so it was pressing against Eren's, as she then clung to him, nuzzling against his arm.

"Oi, Mikasa! We're not in grade school anymore!", Eren said, although he blushed. Armin smiled. "Some things don't change", he said.

"Only I sit next to Eren", Mikasa muttered.

Once everyone took their seats, the teacher, Rico, began name call.

"Sasha Brause", she called. "Here, ma'am!", a red haired girl stood. She had a rice ball in her mouth.

"Sasha, you want to explain why you're eating in class?", Rico asked, frowning.

"Because it was in my bag, begging to be eaten!", Sasha replied simply. Rico frowned.

Sasha gave a nervous grin. "Sasha Brause", Rico stated. "Yes?", asked Sasha.

"You just earned yourself 3 day detention", Rico said. "WHAT?!", Sasha whined, horrified.

"This is high school, not kindergarten!", Rico yelled back.

Sasha sat down, totally devastated. "Listen up, you ungrateful teens, take Sasha's detention as a warning! I don't take any nonsense for any of you! Now, Connie Springer!", Rico yelled.

There was silence. "CONNIE SPRINGER!", the teacher repeated. "Huh? Oh, here!", Connie stood up, he had been dazed off.

"Connie Springer, will I need to worry about you not paying attention in the future?", Rico asked. "No, sorry ma'am!", Connie replied.

"Jean Kirschtein", Rico called. "Here!", Jean said, standing up.

After calling Armin, Ymir, Kristia, Marco, and the rest, she moved on. "Annie Leonheart!", Rico called.

Nothing.

"Oh, Annie's absent today, ma'am", Reiner said. "Absent on her first day of high school? Not a good sign", Rico frowned.

"Mikasa Ackerman", she called. "Here, ma'am", Mikasa stood up. Jean blinked, looking at her. He turned red.

"I want you and Eren Jaeger to uh...separate a bit there", Rico said.

Mikasa hesitated, looking down. "How come?", Eren spoke up. "This is a classroom, not a hang out. You can still sit next to each other, but just...back it up a bit", Rico then pushed their desks away from each other.

Mikasa glared dangerously, but she remained quiet. "Now then...", Rico walked back to the board.

"Hey...it's okay Mikasa", Eren assured her, as Mikasa sat down. He gently gripped her hand. Mikasa nodded, she exhaled, placing her hand on her scarf.

Jean starred, totally confused. "Hey um...they came to school together, right?", he whispered to Marco.

"Yeah...they're siblings...", Marco nodded. "But they have different last names", Sasha pointed out.

"They sure act close for siblings", Jean scoffed.

Eren and Mikasa didn't hear their whispering, as the class began.

When the class ended, students flooded the halls, heading to lunch. Some went to the roof, others to the back courtyard, while a few went to the cafeteria.

As Mikasa exited the classroom first, Eren still getting his papers in his bag, Jean caught up with her.

"Hey um...you're Mikasa, right?", he asked. "Yes", Mikasa replied simply, as she waited for Eren.

"So um...", Jean hesitated, blushing. "What is it?", Mikasa asked, frowning. "Oh...sorry! Just...you have really beautiful black hair", Jean replied.

"Sorry, Mikasa!", Eren came out then. "So you want to eat lunch in the courtyard, Eren?", Mikasa asked.

"Sure!", Eren nodded. Jean stood there, totally dumbfounded, still a bit entranced watching them go.

As Eren and Mikasa walked down the hall, a group of students watched them. "What was up with that girl clinging to her brother like that?", one whispered.

"It's creepy, they came here together...", another mentioned. Eren blinked, hearing them. "Who are you talking about?", he asked.

The girls hesitated, looking uncomfortable.

"What?", Eren asked.

"Well...we're talking about you", one of them replied. "Why us?", asked Mikasa, frowning.

"Well, aren't you brother and sister?", one of the girls asked.

"Actually no", Mikasa answered. "Look, we live together, but we're...", Eren began. "You live together? So then you are brother and sister?", one of them pressed.

Armin came over, overhearing. "No, you girls got it wrong! When we were little, Mikasa's parents passed away, so Eren's parents took her in...", Armin explained.

"That seriously means adoption...", one of the girls stated.

"You got a problem with us, or something? Why would you even care?", Eren snapped, losing his temper. "Eren, please...", Mikasa pulled at his hand.

The girls exchanged looks, and even snickered a bit. They then walked off.

"Yeah, you better run!", Eren yelled, glaring. "Eren, just ignore them. It's not worth it", Mikasa said softly.

"No one picks on my Mikasa and gets away with it!", Eren growled, shaking furiously. Mikasa instantly turned bright red, and even froze.

"Eren...!", she cried, beaming, hearts in her eyes.

"What? You're family", Eren stated looking at her. Mikasa blinked, the hearts leaving her eyes. "Yeah...family", she looked away a bit, sheepishly.

She worried that after all this time...maybe Eren didn't have feelings for her anymore.

"Let's just go have lunch", Armin said.

The trio went to the courtyard, and went under a Sakura tree on the soft grass. Mikasa spread out a picnic blanket.

"The weather's perfect for lunch today, I can't believe anyone would want to eat inside", Armin said happily.

Mikasa sat down beside Eren, opening her bento box. "Hey Mikasa, thanks for making my lunch!", Eren grinned, opening his.

His lunch had cheese burger, small omelets, few vegetables, and rice. Along with two rice balls.

"Your mom was really busy with making breakfast, so it was no problem", Mikasa replied. She had fried shrimp, small omelets, vegetables, and rice, along with a rice ball for dessert.

Armin had a bento box as well, it had sushi, sausages, rice, and vegetables in it, and a rice ball.

"Eren you really should eat healthier", Mikasa stated, frowning at his lunch. "Are you kidding? I wasn't about to pass up my favorite food our first day!", Eren said.

"Enjoy it now, because I'm only packing you healthy food for the rest of this week", Mikasa said.

"Aw come on!", Eren whined. "I got us all drinks from the vending machine", Armin offered a bottle of iced tea to Mikasa, and a Coke to Eren.

"Thanks, Armin!", Eren grinned, while Mikasa gave a smile, taking the iced tea. Armin opened his little juice box.

"We really should start thinking about what clubs to join. We got tons to choose from", Armin said as they ate.

"I'm going to join Basketball!", Eren grinned, excited. "I'll be joining the P.E club, since its in the same building as Eren's", Mikasa replied, as she ate her rice.

"What about you Armin?", Eren asked.

"Well, I'm not as in shape as you two so I think I'm gonna join the Reading club", Armin admitted.

"We should all apply today", Mikasa said.

After lunch, they all went to the clubs to apply. They also found out what clubs their classmates joined. Jean, Connie, Marco and Ymir all joined basketball with Eren.

Krista joined Music, while Reiner and Bertolt joined P.E with Mikasa. Sasha joined the Anime Club (mainly because it meant she could eat snacks while watching anime) while some other classmates joined the Cooking club.

The school day soon ended, but once it did the weather had changed drastically. It was cloudy and dark, as rain fell.

Eren and Mikasa walked home. They had to share an unbrella, since Eren didn't bring his. "I can't believe how much homework we already got! Rico's gonna kill us!", Eren whined.

"It can't be helped, its high school", Mikasa said softly. They had to walk close to each other, to stay under the umbrella.

Mikasa blushed softly, as she glanced up at Eren.

"Looks like we won't be able to take your Sakura flowers to your parents graves until tomorrow. It's too wet out now", Eren stated, looking up at the dark sky.

Mikasa nodded quietly, as they walked home.
