(You are Nezuko)

You were hanging out with Tanjiro, Inosuke and Zenitsu per usual, like always Zenitsu was being a simp and a pervert and it was making you uncomfortable (because who wouldn't be?), Muichiro walked in the room, he noticed what Zenitsu was doing, that it was making you uncomfortable which made Muichiro angry

Muichiro: "Zenitsu leave Nezuko alone, can't you see she's uncomfortable by what you're doing, how do you expect to pull a girl if you act like a perverted crybaby simp"
