Narae should just f off, like, she has no right to interfere when he's doing lewd things with Rangii. She's his WIFE. The mc has no reason to let Narae hit/scold him whatsoever.
Idk why mc even likes Narae... cuz of her body? That's not an excuse to let her treat him like this. If I were him I'd have hit her hard multiple times by now. How can he even let her hit him for no reason??
