Eh, I am not sure I like the mc leaving the room and the wife supposedly thinking that he isn't looking and then doing whatever the hell she wants and not telling anything to the mc. Like, the wife is doing it because the mc likes it isn't she, what is even the point of doing any of this if the mc can't enjoy it fully.
I just can't help but be reminded of japanese nts slop where the husband is literally just a prop. If there is no love between the couple then the netorase doesn't really work at all. Thankfully it seems like there is a scene between the couple coming up.
