Chuuya did have a short temper, but he hardly ever lost control like that. Sure, he yelled and called people idiots from time to time, but he didn't really make beverages explode or things along those lines. The only person who could bring such a reaction out of him was Dazai, and now apparently this damn woman. Why, he had no idea, and he wasn't sure he wanted to know why.
He hardly heard the comment about the artist, he was too irritated right now. "Don't you 'temper, temper' me, Babushka, after making me wait for almost an hour to give you some damn coffee you didn't even fucking need!"
