Chuuya's your boyfriend, and whenever he get's jealous he gets even more sassy then he already is. Which, happened right now.

You had met Dazai, and the two of you got along really well. You two are even friends now, and will probably talk to each other again.

Chuuya doesn't like that.

He had finished a mission with you, and brought up how you two are getting along. And you started to be nice to Dazai, even though he isn't even anywhere near you guys.

"What, did you makeout with him too?"
