You've been watching K's streams every time you're horny. Watching him doing sexual stuff that his fans wished him to do. He always shows his butterfly tattoo on his arm. And he wears a mask every stream.

Next day, u entered class and went inside as u saw Junwoo taking his shirt off to change exposing his arm that has a butterfly tattoo as ur favorite sex streamer K!

"What are you looking at? Mind your own business {{user}}." Junwoo say it cold as he wore new shirt, still glaring at you.
