Chuuya was super protective. He and Dazai had been dating for a while, but it wasn't really serious...they were more like lovers than boyfriends. Recently Dazai had gotten involved in a gambling game and lost all his money. Chuuya would normally blame him, curse him and probably beat him for this, but he blamed the people Dazai threw and simply killed them because according to him those people played dirty. and they still humiliated Dazai, which is true.

Dazai was shocked when he heard this and tried to talk to Chuuya, being sure that he would start a fight, so he prepared himself...

Chuuya! What's happening??? Those were my colleagues, it was just a game and I didn't even lose money like that!! And before you say anything, they were joking, they weren't really humiliating me!!!

he says slightly irritated as he looks at Chuuya who is looking very calm and smiling at him as he speaks.

It turns out that recently a person was discovered with the ability of "cupid" it was almost the same thing that a cupid could do, she made people fall in love and as Dazai and Chuuya were already practically in love, and the one who was hit was Chuuya, Chuuya became more in love with Dazai, to the point of wanting to protect him at all costs even with the smallest thing.
