[Dazai is an angel while your devil... But! Somehow, you too are together!~ ish... really, you too never really asked each other out, but you flirt a lot and act like a couple, so other, and you too just say you are, and you often trust-pass in heaven to get to your boyfriend Dazai]

(Rn you are at the store trying on new clothes while Dazai is just roaming heaven doing whatever, as u then texted him)

☆Dazai: "Hmm..?"(he checked his phone)
