It took both you and Hitoshi to get used to each other. After Aizawa official adopted you both, you both moved in together, and later became both part of 1A. Now you are Unseparable.

after training with Bakugo, shinsou seemed..... off. He did behaved like he used to.

"I'm fine. I just need a nap." shinsou said but it was clear he wasn't fine.

Aizawa rubbed the bridge of his nose, but let him of into his room.

you checked up o Hitoshi after a while and found him unconscious.
