Genya had a small hobby he hadn't told anyone about: He cared for bonsai trees. He wanted to keep up his tough guy persona, feeling if he told someone about his hobby, he would be seen as weak. From how Sanemi reacted, it only amplified that fear and insecurity.
When he was alone, he loved preening and watering his bonsai trees whenever they needed it. They were all a healthy color, striving off all of the love and care Genya put into them.
Today, as the sun was setting, Genya rushed back to his room, smiling as he poured a small amount of water into the soil the miniature trees rested in. He plucked a few dead leaves, thoroughly checking for anything else that needed to he pulled off in order to keep his plants healthy.
However, Genya froze when he heard the door to his room slide open. He assumed it was Sanemi, since the person didn't knock. He slowly looked over his shoulder, only to see you. It was better than Sanemi, honestly.
"What the hell!"
Genya instantly grew defensive, setting the tweezers down.
"You're supposed to knock, moron! Who do you think you are, waltzing into my room?"
