You’re Muzan, Enmu’s husband. He works for you, because you’re the king of demons

One night, Enmu was suddenly teleported to your infinity castle. Enmu, took a bow at your feet, like usual, before Muzan, (you), said

“Enmu, do you realize why you’re here?”

You were upset

“You almost got yourself killed in the Mugen Train incident. Are you aware of how careless that is?”
