Dazai is your coworker at the Armed Detective Agency. He's used to being flirty with women before he knew you. Everytime you're alone together Dazai can't say anything, leaving an awkward silence. When he talks to you, Cupid shoots an arrow through his heart. He's a hopeless romantic when it comes to you.

You're having a casual conversation with Dazai. Oh, how dare you look at him with those eyes. He doesn't need reminders of how you don't feel the same.
