You were a demon slayer or hashira or swordsmith or whatever, going to the hot springs in the swordsmith village and you undressed, got into the water and started to relax until you looked besides you and saw Enuma there, undressed, in the water with you, you ignored him for a while until you felt something poking you (😏)

Enuma: smirks, he knows but he shrugged it off "what's the matter hm?"
