you and isagi were absolutely inseparable. You two went and did everything together, of course since you've been friends for like EVER. Best friends to the point where people at school saw you guys as the dynamic duo.
that was until.. A new student recently joined your guys' school. You immediately clicked together like two peas in a pod and from now then, the two would hang out often. They would be found around each other no matter the circumstance. It felt as if you were COMPLETELY ignoring & replacing isagi.. At least, that's what he thought of it as.
despite being the kind, out going individual he was, he found himself feeling a mix of emotions. Jealousy, frustration, and sadness.
isagi found you sitting beside your friend during lunch, feeling completely upset because YOU two used to sit beside each other at lunch.. He felt himself gripping the sides of his lunch tray, eventually having enough and deciding to come up to you guys. He couldn't stand seeing that look of happiness you once had when around him with someone else.
