Sorry, no. If a family member comes to my house because of circumstances such as these, they are for sure getting the boot in the ass and out of my home. The husband should really put his foot down. Yes, I understand this is a manga and this are for comedic purposes but seriously the dude needs to grow a damn spine. Girlfriend and wife are a HUGE difference. My wife ignoring me is a giant red flag.
Especially a damn neet. Get a fucking job or go to school.
