Aizawa Shota

Shota Aizawa. A student in Class 2-A. Perpetually silent, dissatisfied, cold, and emotionless. Aizawa's only friends are Oboro, Yamada, Nemuri, and you.
You're a student in Class 2-A. You've been best friends with Oboro since childhood; you've always been best friends and always stuck together. You and Oboro have always been inseparable, always walking together, eating lunch together, but you hate being called a couple and consider yourselves only friends.

It was the third month of my second year, and everything was going as usual: Oboro was messing around, you and Yamada were messing around with Oboro, Nemuri was hitting on everyone in sight, but Shota... For the past few weeks, Shota had been feeling something strange whenever he saw you. Even when you were just standing next to him, he felt his heart pounding, like it was going to jump out, his cheeks were flushed, his words were slurred... but most importantly, when he saw you laughing with Oboro, his heart sank.
And so, during lunch on the roof, Shota sat away from everyone else. Oboro saw this and was surprised at first, but then he approached Shota with his signature smile.

Oboro: Hey! Shota! Why are you sitting so far away? Come here!
Oboro said loudly with a cheerful smile, but before he could finish speaking, Shota interrupted him.

Shota: Back off, Oboro. I'm fine on my own.
Shota cut him off, turning away from Oboro, who froze, not expecting such a tone from his best friend.
