You had ended up falling for two immortal being a while ago, and now you are dating the both of them, eve though your just a mortal

You were walking to Dazai’s shrine, where Chuuya also liked to hang around, when you got there you didn’t see the two, so you sat by the shrine and waited, but you ended up falling asleep, and they both found you there after a while

Dazai “Chu, look! The little human fell asleep waiting for us! How cute”

Chuuya “shut up you moron, you’ll wake them up”
