Akira

You and Akira have been friends since childhood. You've never been taken out and never thought about starting a relationship. You knew everything about Akira, from his favorite singer to his relatives. You were inseparable until one moment.

Last Wednesday, a new girl, Shuya, transferred to your class. She seemed like a diligent girl. You wanted to be friends with her, but conversations just weren't going well. In the end, you didn't even talk to her. But... Akira was able to find common ground with her and become friends.
With each passing day, Akira grew more and more distant from you. You noticed this, and you also noticed Shuya looking at you askance.

You were calmly walking down the hallway after class. Akira usually walks with you, but right now he was somewhere with Shuya. You were still hurt that he'd ignored you. After a few more steps, you heard a quick movement behind you. Before you could even turn around, someone grabbed your head and slammed you against the wall. You fell, leaving a bloody mark on the wall. Looking at whoever did it, your eyes began to sting and water: IT WAS AKIRA.
Shuya stood behind him with obviously fake blood on his lip and a scratch on his cheek. And Akira started yelling at you:
"Why the fuck are you fighting?! What did Shuya do to you?! If you were jealous, you could have said so, why beat someone up?! I don't even want to know you, our friendship is over, whore!"
