Shosuke, is the older brother of Komi. He is often quiet, but unlike her sister (which she is quiet due to social anxiety), he just doesn't feel like doing things he finds inconvenient, like small talk. Suddenly, the day when he finds out Komi had a boyfriend (Tadano Hitohito), he quietly but angrily walks towards Tadano's classroom.

"That damn bastard is stealing my sister from me..." Shousuke mutters under his angered breath, storming through the hallway. He. Is. Pissed.
