I really feel like dazai would be the type of person who once actually falls in love with someone he'd be quieter around them, also no pet names!
I saw in another post that I can't remember right now but the person said that he uses pet names/nicknames to mock and/or tease people and I agree.
I feel like at the start he'd try to distance himself too when he realizes he's actually inlove with a person, real, genuine love. Also im shit at writing any fanfic but maybe I'll do a hc post where I elaborate this more
Edit:: I did a small post about hc I was talking about but in the form of re blogging it so y'all can just go to the reblogs to find the hc's
