THE REASON

Tsuna and Kyoya were at the playground near Nami Middle. The two of them were the only ones who were there which was good for Kyoya because it makes him feel more comfortable since he doesn't like crowds. However, for Tsuna, it looked very bad that not one person was in sight. Tension and nervousness were the things Tsuna was feeling the whole time he's with Kyoya, maybe because he's thinking that being alone with the disciplinary committee chairman is probably one of the most dangerous thing he's done and also, if Kyoya gets a bad reaction from what Tsuna's about to tell him, Kyoya might bite Tsuna to death. What's worse is that since there were no people around, no one will be able to come and help him. The more Tsuna thinks about these things, the faster and louder his hearts beats. He could feel his sweat pouring from his head and his hands shaking. Somehow, Tsuna wants to back out on what he's about to do.

'Get a hold of yourself Tsuna! You can do this! I mean it's not like what I'm about to say will make Hibari-san angry that he'd bite me to death, right? Right?' Tsuna thought. While Tsuna was debating with himself, Kyoya spoke.

"How long are you going to keep me waiting for your explanation. If you aren't going to say anything then I'll leave" He said as he was getting impatient.

"Ah..R-right…I'm sorry about that, Hibari-san" Tsuna said, avoiding Kyoya's glare by lowering his head

'Alright, I guess there's no turning back now. I'm sorry Dino-san but I really need to tell Hibari-san the truth.' Tsuna thought as he raised his head

"….On the day you had the accident, you remember right? That Dino-san was there? He was also the one who took you to the hospital"

Tsuna didn't think that Kyoya would answer his question so he just continued to what he's saying.

"When we heard what happened to you, me and reborn immediately rushed to the hospital…"

"Dino-san!" Tsuna, who was running in the halls of Namimori hospital, called out as he saw Dino sitting on the bench near the operating room.

"Oh Tsuna, it's you.." Dino said with a low and flat voice

"Dino-san, how is he? How's Hibari-san?" Tsuna asked while he was panting.

"The operation still isn't over. It's been like this for almost an hour"

"How did this happen?"

Dino stayed silent for a minute. Tsuna could see how Dino's face turned from expressionless to being in pain.

"…It's all my fault. If I hadn't lost it and said hurtful things to him, he never would've run from me and get hit. This happened to him because of me."

Tsuna was curious of what Dino said to Kyoya but he didn't ask because he doesn't want to upset Dino even more. He decided to keep quiet and to not ask anymore questions.

While they were waiting outside the operating room, Tsuna could notice how Dino was getting impatient. To Tsuna, it looked like every second of waiting is agony for Dino. Also, Tsuna noticed that Dino stands, walks around then sits back again for every 5 minutes or so.

The second they heard the sound of the operating room door opening, Dino immediately stood up.

He looked like there was this big rock crushing him but now it has been lifted, but only a small portion of it. There's still a bigger portion that's crushing him and it won't be lifted until he make sure that Kyoya is safe. As soon as he saw the doctor coming out, he hurriedly approached him, dying to know how his beloved Kyoya is doing.

"Doctor, how is he?" Dino asked.

"The operation was a success but I'm afraid he has fallen into a coma. The head concussion he received in the accident was a bit severe. We can't guarantee how long he will stay like this."

Dino looked like the portion of the rock that's been lifted from him crushed him once more, only it became bigger.

"Doctor, will he ever wake up?" Dino said in a coarse voice.

"There's a big chance he'll wake up but we don't know when though. Only…there's also a chance that if he wakes up, he'll have amnesia."

Dino didn't respond anymore. He looked like he was in a daze

"The nurses will move him into a private room later then I'll give him some tests. You can see him after that. "

"Ah T-thank you, Doctor" Tsuna said since Dino's still deep in thought.

After the doctor was done giving tests to Kyoya to reassure that he's now out of danger, he allowed Tsuna, Reborn and Dino to come see him. There are three people who waited when Kyoya was having the operation, but only two of them visited him inside his room. The other one who probably was the most important person to Kyoya and should have been the first one who went in the room to see him decided to stay outside near the door.

He wanted to enter the room and see him. He wanted so badly to make sure that the one he loves was fine. Well not technically fine but at least he wanted to make sure that he's out of danger, with his own eyes. But no matter how much he wanted to, he can't. After all, for him, it was his fault this happened. Why should he be permitted to see him if in fact, because of him, this happened to Kyoya. As minutes passed, there were so many times when he couldn't take it anymore and just decides to go inside the room already but hesitation comes every time he tries to touch the knob on the door. He got preoccupied with trying to restrain himself from opening the door and entering the room that he got a bit startled when he noticed that there was a boy with spiky hair coming out of the door.

"Dino-san?" Tsuna said.

"How is he?" the man who refused to go inside Kyoya's room asked.

"He's sleeping peacefully inside. I think his condition's already stabled. He's out of danger just as the doctor said"

"Really?" Dino said with a hint of relief and joy in his reaction.

"Yes"

Dino gave out a big sigh. What Dino heard from Tsuna was enough for him to be at ease or at least, it should be enough for him.

"That's great…well then…I think I'll be going now" he said, as he gave a pat at Tsuna's shoulder and started walking towards the nearest elevator.

"Wait Dino-san! Aren't you going to see Hibari-san?"

"You said he's okay right? There's no need for me to see him…besides, I probably don't even have the right to see him after what I've done."

Tsuna watched him go towards the elevator. He wanted to stop him and convince him to see Kyoya first but he felt like he wouldn't be able to convince Dino even if he tried. When the elevator door opened, Dino called out to him.

"Tsuna…can I have a favor to ask?"

"What is it?" Tsuna replied.

"Would it be okay to check on him once in a while? Would you watch over him for me please?"

"Huh?" As confused as he was, Tsuna had no choice but to accept Dino's favor "…okay, I will." Tsuna said even though he wasn't sure of what Dino meant when he said those things.

"Thank you. I'm counting on you, Tsuna" Dino said with a smile on his face. It wasn't a smile of happiness but it was more of a pained smile. After saying those words, Dino went in the elevator and left the hospital.

"After that, Dino-san didn't come and visit once. He just calls me and asks how you were. At first I thought that he was just busy with his work but then I soon realized that he purposely didn't go to the hospital to see you. He was too guilty with what happened to you that he couldn't forgive himself.

"When we found out that you lost your memories, we immediately called Dino-san but we couldn't reach him even if he was still in Japan. We only got a hold of him a few days after you woke up. There was one time, outside the gates of Nami Middle, Reborn and I was about to go and visit you at the hospital after school when Dino-san suddenly showed up"

"Hey, Tsuna!" Dino called out.

"Dino-san? What are you doing here?"

"I came to say goodbye. I'll be flying back home to Italy today and I think it will take a long time before I could come back to Japan again."

"W-what? But how about Hibari-san?"

There were other things that Tsuna wants to say to Dino regarding him leaving but Kyoya's situation was the first one that went on his mind. He couldn't believe that Dino would just decide to leave like that without confronting his situation with Kyoya.

"I went to see him a while ago to say goodbye as well. Fortunately, he was asleep when I came. I intended for him not to know I went there or else he might ask who I am"

"Huh? You went to see him? Wait, why don't you want him to ask who you are?"

"….because… I don't want him to remember me…"

"What do you mean?" Tsuna asked, confused.

Dino was silent for a while. His silence lasted about more than 5 seconds more or less.

"I realized…that it's better for Kyoya not to remember me. I'll only bring him pain if I stayed by his side. I'm not good enough to be his lover. I didn't even listen to him when he tried to explain to me why I saw him with Mukuro. Instead, I just judged him."

"But Dino-san-"

"I think its better if Kyoya didn't remember a person like me. It's better if he finds someone else. That's why I'm moving far away from him and that's why…it would probably be the best if you guys never mention my name or anything else about me to him"

"Is that what you really want, Dino? You know that there could be consequences with your decision. Even if we deny your existence to Hibari, there's still a chance he might remember you someday" Reborn, who was quiet the whole time, finally spoke.

"I'm aware of that. If ever the time comes that he finds out who I am and gets angry at me and starts to hate me, then I'll accept it. I'll accept that… as my punishment" Dino said.

"Hmm…well alright then. We'll do as you wish" Reborn calmly said

"Reborn!-" Tsuna tried to disagree but Reborn interrupted him.

"This is Dino's decision. We can't stop him" Reborn said

Tsuna was shocked with how Reborn is taking all this. He was wondering how he could agree with what Dino decided so fast. But then again he's thinking that Reborn is really like this. There are just times when he can be so unreasonable.

"Thank you. Well then, good bye Reborn, Tsuna. I'll miss you guys"

A car came to pick up Dino to the airport. As Tsuna saw him going farther away from them, he can't help but think about Kyoya. How could he just hide Dino's existence from Kyoya even when he knows how important Kyoya is to Dino and vice versa.

"Reborn, is it really alright for things to be like this?"

"…Who knows…but Dino was the one who made this decision. No matter what the outcome is, it's his responsibility. This is something he and Kyoya should face."

"And that's the whole story…"Tsuna ended.

Tsuna was waiting for Kyoya's reaction but the cloud guardian was just silent there, then, he was startled when he heard Kyoya chuckle. Then he started to talk.

"Hm! I see. So that's what happened…that coward…he was too guilty to face his own mistake that's why he selfishly asked you to hide the truth from me and ran away to Italy. Hm! I understand perfectly"

"What? No you don't understand! That's not what I meant-"

"Shut up!" Kyoya said and turned his back on Tsuna. "I don't want to hear anymore. I'm going"

"Hibari-san, wait! Dino-san lied because he thought he wasn't deserving for you and it would've been better if you forget the pain he caused you! He was only thinking about you!"

Kyoya has had enough with what Tsuna was saying. He doesn't want to hear anymore from him. No matter what Tsuna said to him, Kyoya just ignored him and kept walking.

At last! I finished it! It took me like one week to finish this. *sigh* Curse my laziness! This is the most challenging chapter I've done so far. I'm just so glad it's finally done! Just ask me if you're confused about something. Thanks for reading!
