Modern au
Genya is 16 and Muichiro is 14

It had been a while since Genya had liked Muichiro. He believed that the two were best friends, but instead the feelings that the eldest had for him were deeper.

There was just one problem.
Muichiro already had a boyfriend.
A boy named Aku, a year older than him, who seemed to really love him when they were in public.

<<Mui, but... do you love him?>> Genya asked him once, while they were sitting together at lunch during their lunch break. The question had taken the younger one by surprise.

<<Y-Yes, of course! He's my boyfriend!>> he said, but looked away.
<<Whether or not he's your boyfriend doesn't mean you have to love him>> he observed, trying to meet his gaze.
<<What is it, are you jealous?>> asked suddenly Muichiro, in an angry tone.
By this time the two had changed the subject.

However, when he got home, Genya asked his brother if he could talk to him.
<<Nemi... do you know my best friend, Muichiro?>> he asked, after they had sat down on the couch.

<<Yes, the one with the long hair?>>
<<Exactly. Well... he's engaged to a boy who... I don't know... I don't like very much>>
<<Well, you don't necessarily have to like him...>> Sanemi commented.
<<I mean, today I asked Muichiro if he loved him and he... looked uncomfortable>>

<<Oh>> Sanemi reflected for a moment.
<<How is it with Muichiro in public?>> he asked then.
<<He fills him with fuss, but he seems... he seems to be pretending...>>
<<You like Muichiro, don't you?>>
<<Well, yes...>>
<<Maybe then they are just sensations. Maybe you're just jealous.>>

Sanemi ruffled his hair and got up from the sofa.

<<Maybe...>> he murmured, before getting up in turn.

The next day at school, Genya waited for Muichiro to arrive, and when he arrived, he met him:
<<Hey Mui!>> he greeted him with a forced smile, but then stopped.

<<Hello Genya... are you alright?>> asked the youngest noting the his worried look.

<<What happened to you?>>
Muichiro had a dark red mark under his eye, a bruise.
<<Oh...this?>> Muichiro pointed at him smiling.
<<It's nothing ... last night I slipped on the stairs and hit the railing>> the boy chuckled.

<<Mmh, are you sure about that?>> Genya asked touching him gently.
<<Yes, it's ok!>>

<<Well, ok... now I have to go. See you during the lunch break?>> asked the older one.
Muichiro looked sorry.
<<I... promised Aku I'd spend it with him... sorry>> He lowered his head.

Genya did not answer right away.
<<...Okay. Don't worry>> he then said flatly.
Muichiro looked at him, he understood that he was hurt.
<<Genya, really, I'm sorry... can we do it tomorrow?>> he asked, clinging to his arm in a pleading tone.

Genya forced a smile.
<<Yes, of course. Don't worry>> he stroked his head, then walked away.

After school

<<Hey, Genya!>> Aoi called to him.
<<Hello...>>
<<Are you coming to have lunch?>>
<<Yes>>

Aoi looked at him better.
<<Are you okay?>> he asked.
<<Yes, sorry>>
<<Ok... where is Mui?>>
<<He was busy with his boyfriend...>> replied Genya in an angry tone.
<<Ah, I understand... Let's go>>

Aoi and he approached the table where their friends Inosuke, Shinobu and Mitsuri were.
<<Hello guys!>> Mitsuri greeted them waving her hand.
<<So, how did the lessons go?>> Shinobu asked, as Gebya and Aoi sat down.
<<As usual>> Genya answered simply.

<<Hey, where's Mupoichiro?!>> Inosuke asked looking around.
<<His name is Muichiro, Inosuke>> Aoi corrected him with a chuckle.

<<Anyway he was busy>> answered the girl.
<<Ugh, I wanted to have his phone number. He's nice, you know?>>
Then Inosuke turned to Genya.
<<Is that your boyfriend?>> he asked.
Mitsuri choked on a piece of Daikon.
<<E-Eh?! Since when?>> he asked coughing.

<<No! We're not dating!!>> Genya exclaimed with red cheecks.
<<Well, but you like him...it's obvious>> Shinobu commented smiling.
<<What are you saying?!>>
<<I'm sure you'll make a nice couple!>> Mitsuri exclaimed.

<<Actually, Muichiro already has a boyfriend>> Genya specified dryly.
The others looked at him without saying anything.

After a few minutes Nezuko and Zenitsu also joined the group and everyone started chatting again as if nothing had happened.

At some point Genya stood up.
<<Where are you going?>> Mitsuri asked looking at him.
<<I'm going to get a drink from the vending machine. Anyone want something?>>
<<Can you get me a coke?>> Aoi asked.
<<Sure>>

Genya left.
He actually just wanted to be alone for a moment.
He was in a bad mood knowing that Muichiro was with his boyfriend and not with them.

You're too jealous, Genya, he told himself. Stop that.

He arrived at the vending machine. There was no one around.
Genya took two cokes, one for himself and one for Aoi, then leaned against the wall.
He stood there for a few minutes doing nothing, then drank his coke and threw the can away.

Before he could leave, however, noises caught his attention.
Genya leaned over the wall, there were two people... and when he realized who they were, Genya was shocked.

They were Muichiro and Aku. They were kissing, attached to the wall, the oldest against the youngest.

Genya looked at them with hatred. Why couldn't it be him instead of Aku?!
<<Ugh, who knows what he has that I miss...>>

The boy didn't think it would be very appropriate to stand there and watch, but he couldn't take his eyes off the scene.

Finally the two separated.
Genya hid as best he could behind the wall, but neither of them seemed interested in him.

He noticed that Muichiro was panting hard, which made him feel great disgust for Aku.
However...
Muichiro was painting a little too hard...

Genya tried to look and listen better. Aku was saying something to Muichiro.

<<Have you talked to anyone about it?>> he asked him without removing the body from his.
<<N-No...>> Muichiro whispered, so softly that Genya could hardly hear him.

<<Are you telling me the truth? You know...>>
Aku ran his hand over Muichiro's thigh and patted hard.
<<Do you know what would happen?>>

Genya froze.
What is going on? What does all this mean?

<<Please, Aku...>> Muichiro said in a low voice.
<<I didn't hear you... you have to speak louder>> the boy grabbed Muichiro by the hair and jerked him.
<<Come on, Muichiro. Say it again. Beg me... I like it when you do~>> Aku kissed him again, rather rough, almost violent.

<<A-Ah... you're hurting me!>> Muichiro exclaimed trying to take his face away from hims.

Genya looked away. Aku...he abused Muichiro...all that time, and he never knew it...
He covered his mouth with a hand and looked up at the ceiling to keep the tears from filling his eyes.

Moments later he heard a thud, and when he turned around he saw Muichiro on the ground, with his back against the wall behind him and his attacker crouched in front of him.

<<Open your mouth>> he ordered.
<<N-No...>>
<

<Do it!>>
<<I don't want to!>> Muichiro yelled.
<<Shut up, slut!>> Aku kicked Muichiro in the stomach, making him cough.

<<Do what I tell you or it will end badly, you know it!>> the older one raised a hand on him, ready to hit him, Muichiro raised his arms trying to protect his face.
<<Ok, ok!>> he exclaimed, terror in his voice.

Aku chuckled.
<<Excellent choice>>
Genya watched in horror as the boy began to undo his belt in front of a violently shaking Muichiro.

Shit, why am I not stepping in?!
Genya suddenly wondered, but at that moment footsteps were heard along the corridor.
Aku froze, then put his belt back on and tried to force Muichiro to get up, but Genya finally decided to enter the corridor, walking as casually as possible and pretending not to have noticed anything.

As soon as he saw him, Aku let go of Muichiro and he too started walking as if nothing was in the opposite direction.

Muichiro got up shaking and when Aku was far enough Genya joined him.
<<Mui!>> Genya hugged him even before the boy could understand who he was.
<<G-Genya?>> Muichiro tried to speak normally, but to little avail.
<<Sorry...! I should have intervened immediately... I don't know what blocked me!>>

<<Intervene? What are you talking about?>>
At this question Genya left him and looked at him irritably.
<<Stop pretending. I saw what he did to you>> he said ceasing to hug him, but without letting go.
Muichiro's eyes widened and they filled with tears.

Genya hugged him again.
<<Everything is fine ... I'm here ... you should have told me before ...>>
<<S-Sorry, sorry! I was scared... he always hurts me!>> Muichiro started sobbing into his shoulder.
<<I don't want to do it anymore!!>>
<<Yes... I'll take care of him, don't worry>>

Genya kept holding him tightly, stroking his head, while he kept crying and shaking.

It had been three days of the incident. Genya had always kept Muichiro busy so he couldn't see his 'boyfriend', and so he would be in no danger.

During the lunch break that day, Genya saw Aku walk by the table where he, Muichiro and their other friends were sitting. He felt hatred grow inside him, until he decided to get up and joined him.

<<Hello... you're Aku, aren't you?>> she asked him with a friendly air.
The boy motioned to his two friends who were with him not to wait for him and gave him an unenthusiastic smile.

<<Yes, it's me. How do you know me?>> he asked.
<<You're my best friend's boyfriend, aren't you? His name is Muichiro>> said Genya.
<<Ah, yes, he had told me about you... what's your name, sorry?>>
<<Genya. I'm going to the vending machine, would you come with me? So we get to know each other better>>
<<Okay!>>

The two walked together While Genya smiled, however, he was hiding feelings such as hatred, disgust and anger.

When they arrived they each had a drink and stopped to chat. Genya just wanted to make Aku believe that he could be trusted.

<<I have to go to the bathroom, would you wait for me outside?>> he then asked.
<<Sure, go ahead>> Genya smiled, but once making sure that the bathroom was empty, the older boy closed the door behind him.

<<What are you doing?>> Aku asked nonchalantly.
<<You're not deceiving me, you know that?>> Genya said in a harsh voice, catching the boy by surprise and making him turn around.
<<E-Ehh??>> he asked confused.

<<You're a bastard!!>> shouted Genya rushing at him and making him bang his head against the wall.
<<What the fuck?!...>>
<<I know what you did to Muichiro...I saw it...>> Genya punched him in the face.
<<You deserve only to die!>>

<<Let me go!>> Aku yelled, earning only more punches, until Genya's hand started to get bloody.

<<So, Aku...>> Genya grabbed the boy by the collar and forced him to look into his eyes.
<<I want us to make a pact now: we will denounce what you did to Muichiro, and you... well, do as you like... you can also tell everyone that today I reduced you to this, but I don't know if you it's better...>>

He ruffled his hair and the youngest coughed.
<<You must never go near Muichiro again. Do you understand me?>>
<<Yes...>> croaked the boy.
<<Good>>

Genya washed his hands of Aku's blood and came out of the bathroom, walking towards the table where his friends were eating.

<<Hey! Where have you been?>> asked Muichiro.
Genya thought it would be very satisfying to say "I've been hitting your abuser," but he held back...even if Muichiro would find out one way or another.

<<It doesn't matter... Anyway, I was thinking, would you like to go out with me one of these days?>>

SO:

Sorry. I'm sure there are tons of grammatical errors but I don't feel like double-checking and correcting them, because in Italy it's now 1.00am, so I want to go to sleep 🥹
