| Tenma's Pov |

My heart started to beat fast as I looked at (Y/N). She doesn't remember me..

"Can I talk with your doctor outside?" I asked him and he nodded. The two of us went out from the room.

"What's wrong with her? Why can't she remember me?" I asked the doctor who sighed.

"Before you got here, we asked her where she lives, her name,  everything. She remembers them perfectly, so I thought everything is fine. But it appears that you're the only one that she's forgotten. I think it's a selective amnesia. I guess that she erased any memories of you from her memory." He explained and I looked down.

'I can't believe this..my own girlfriend doesn't remember me anymore. Is this my punishment?' I thought.

"Don't be so down now. You can still try and make her remember you. But don't force her much. Just start piece by piece" The doctor suggested and I nodded.

The two of us went back to the room.

"So, you haven't answere my question yet. Who are you?" (Y/N) asked me. It pained me to learn that she doesn't know me anymore, but I must be strong. For her and for me.

I gave her the biggest smile I could do.

"My name is Matsukaze Tenma and I'm your boyfriend" I said and she looked at me confused.

"Boyfriend? I never had a boyfriend.." She said.

"It's because you have a selective amnesia. You remember everything except for him. But it can be fixed. But if you want to remember him, you must take small steps or else some minor effects will happen" The doctor explained.

"I wonder what happened. Oh well, it's nice meeting you, Matsukaze-san" She said.

"Please, call me Tenma. It's kinda weird for me to hear you calling me by my last name" I said to her and she nodded.

"Ok, Tenma-kun" She said and smiled.

"I'll leave you two for a moment. Excuse me" The doctor said and left.

"So, tell me. How long have we been in a relationship?" She asked me.

"Two years and two months now" I answered. (Y/N) looked at me in surprise.

"That long? Wow, we must be really in love back then" She said.

"Yeah.." I replied.

"I'm sorry" (Y/N) said and I looked at her.

"Why are you apologizing?" I asked.

"Because I don't even remember my boyfriend. It must be painful to see that the person you love forgets about you." She said. I smiled and held her hand.

"Don't worry. Everything will be ok. Like the doctor said, you can still remember me. So don't lose hope" I said and she smiled back. After that, we kept talking until it was time for me to go home.

(Yeah, so basically he skipped school and spent his entire day at the hospital)

| No One's Pov |

Another week has passed and you were finally released by the hospital. Your parents soon learnt about your selective amnesia and now they're very protective to you. But they can't really protect you when they have work and you have to go to school. So they intrusted (?) you to Tenma.

Today was your first day of school again.

"Nervous?" Tenma asked you as you two walked. You nodded.

"A little bit" You answered. Even though your friends, except Aoi, visited you from time to time, you were still nervous. You didn't know what the other students will say to you. Your friends discovered about your problem and said that, they also would help you recover all the memories of Tenma.

But there's something that they didn't know. The real reason of your accident. They only knew that you were hit by a truck while walking, but they didn't know that you ran away from seeing Aoi and Tenma kissing right in front of you.

"Don't worry. I'm sure by next week, everything will go back to normal" Tenma reassured you.

"Thanks, Tenma-kun" You thanked him.

As you two walked, two boys walked towards to your direction. It was Shinsuke and Kiriya.

"Ah! (Y/N)! You've returned! It's so good to see you, again!" Shinsuke said and you smiled at them.

"Good Morning, Shinsuke, Kiriya" You greeted them.

"Ready for your first day again?" Kiriya asked.

"Yeah, but I'm still nervous. It's been a while since I attented school" You answered.

"Don't worry! If someone is rude to you, we'll chase them away!" Shinsuke said and you smiled at him.

"Thank you" You thanked him, then you turned to Tenma.

"Hey, how come I never saw Aoi? I noticed that she hasn't visited me. Is she busy or something?" You asked him. Tenma's eyes widened a bit.

"A-Ah. I think she was busy with school" Tenma lied.

"Yeah! School has been very hard for the past weeks" Kiriya said, backing up Tenma who thanked him mentally.

"Oh.." You said.

You didn't remember that you saw them 'kissing' and Tenma doesn't know what to do if you ever remember that. But he knew you're bound to remember that, after all, that was the reason why you lost your memories.

"Why don't we go to our class!" Shinsuke said and Tenma nodded.

"Y-Yeah! We'll be late" Tenma said and you four went in to the school.

| Time Skip |

It's been weeks since you have returned, you and the others went to the field. It was time to train and you were going with them to watch them practice. During your return, You noticed that Aoi hasn't talk to you, not even glancing at you.

You tried to speak with her, but everytime you tried, she would say she had to do something or just walk fastly away from you. You noticed that Tenma has been acting weird too. Whenever you speak how Aoi ignores you, he would looked away or changed the subject. It was very suspiscious to you.

'I know they're hiding something from me..' You thought.

"You feeling ok, (Y/n)?" You heard Kirino asked. You smiled at him and nodded.

"Y-Yeah. Everything is fine" You answered.

"Are you sure? If you're feeling tired, I could always accompany you to your house" Kirino said, looking worried and you shook you head.

"Don't worry, I'm fine" You said.

Kirino was your childhood friend, and you two were very close. He was the one to know about you dating Tenma. While talking with Kirino, you didn't notice that Tenma was looking at you both with a frown.

Tenma knew that Kirino was only your best friend, but he couldn't help but to feel a little bit jealous.

"It's nice to see her here, don't you think?" Tenma heard someone. He turned around and saw Aoi.

"You do realize that her losing memories of me is your fault?" Tenma rudely asked.

"Doesn't matter now. Look, I think she's moving on a bit fast" Aoi said and Tenma looked at you and Kirino again.

"I think it's best for you to move on too. It's pointless to hope that she will remember again" Aoi said and Tenma glared.

"If you think that it will give you a chance then you're wrong. I only have my eyes on (Y/n)" Tenma said and Aoi smirked.

"We'll see about that" She said and kissed him again.

Sadly, you and Kirino saw them kissing. You gasped. Tenma quickly pulled away and pushed Aoi.

"What is wrong with you?!" Tenma yelled and then looked at your side. He saw you with eyes widened.

'Oh no..' Tenma thought.

"(Y-Y/N), it's not what you think!" Tenma said but you didn't listen and ran away.

"(Y/N)!" He yelled your name and chased you.

It was like, it happened again. Just like before. You seeing them kissing, running away and him chasing you.

'I won't let it repeat! I have to reach her! I have too!' Tenma thought.
