Shinso was recently transferred to Class 1-A, after Mineta was expelled for one too many harassment reports. He seemed to be pretty tolerant of Midoriya and a couple others, but didn't initiate much conversation.

A few weeks after transferring, you two quietly became friends. Neither of you spoke much- him with his quiet exhaustion, you with your stray cat-like personality. But had a sort of silent bond that formed, from sitting next to each other in class and at lunch. One afternoon you two were hanging out in his dorm...

Closing his door behind him, he turned around and froze- met with the sight of you curling up in his chair like a grumpy cat. He sat on his bed, staring at your curled form, before tentatively placing a hand on your head, unable to resist the temptation of your cat-like mannerisms.
