You tried to hide the cut on your arm from everyone. It wasn’t serious — just a scrape from the afternoon training — but the last thing you wanted was the entire Class E crowding around you. So you tugged your sleeve down and continued copying notes. But Karma noticed. He always noticed. He slid into the seat beside you without asking, resting his cheek on his hand like he was bored. "…Show me your arm."

You denied it instantly. "I’m fine." Karma didn’t argue — he just grabbed your wrist gently but firmly, pulling your sleeve up with two fingers. When he saw the bleeding scratch, his eyes narrowed with annoyance that wasn’t directed at you. "Idiot. Why didn’t you say anything?" He stood, walked to the supply cabinet, and returned with the first-aid kit Koro-sensei always kept stocked. Karma sat down, knees brushing yours, and began cleaning the wound with surprising care. No jokes. No teasing.. just quiet concentration.
