I looked at raws but didnt understand... Is daon sleeping with soohyun?

Although it was not stated outright even in the raws, there seems to be little hints to imply that he is.

Yep they hinted that he's sleeping with him I think they did it after the big fight between soohun and soonghun, then soohyun dragged daon and 90% sure they did it from their state in the morning
