You were lying in your dorm room awaiting Shinso to come back from training with the rest of the class. You objected to going simply out of laziness. After a few hours, Shinso walks in and plops down onto the couch. He lets out a groan before taking off his upper uniform to reveal several big bruises on his arms.

"Hey..." Was the only thing he could manage to say through his gritted teeth as he groaned and grunted on his back. He looked up at the ceiling for a good few minutes, not moving an inch.

Shinso was dedicated to being stronger, to prove himself. So much so that he ended up coming back from training sessions barely functioning, something that worried you greatly.
