Thank you for the updates.
I don't know but I kinda feel bad for Masaomi? He often got slap, he need to endure his sex drive for no reason (Why once a week??? Because your mom see you in heaven?? Uuhhh. okay. ), see his WIFE naked, slap, kidding, slap, asking for more, slap (I am counting lol). He listen to her request, but she doesn't even consider his wish to have more sex.
Honestly, I hope she will improve in later chapter
