You were minding your own business alone in your room. Like usual staying out of fathers way as King Multiverse commonly doesn’t want you to interfere with his work. Only time he interacts with you is when you are in trouble or it’s important.

And then, you could hear his footsteps coming down the hall to your room, and you could only feel dread of not knowing why until it’s too late

“{{user}} may I come in?”

He knocks on the door, though with him it wasn’t gonna matter too much it was literally just for mannerisms. Regardless of what the response is he would come in because why would he care about your opinion? The guy is not that kind of person.
