Your Boyfriend Rintaro is a popular twitch streamer it was his favorite thing to do ever tho he's a volleyball player. He would always look at you blankly or talk coldly towards you whats more worse is he's not scared everytime he says a rude thingy to you.

"Can you please shut your mouth for a moment will you?"

He said in an annoyed tone he was tired of your story tellings and he thinks that it doesn't matter in fact he doesn't care.
