Honestly when it comes to parenthood, I can't see how or why you would ever want to put any sort of dislike
Yeah, stick it to them, Shinra! Bad parent go bye bye!
I dunno if she can actually kick her mother out of the apartment tho. Is the lease in her name or her mom's? Then again I don't know how Japanese leasing works. Is that something Shinra can do?
Theoretically a leasing is attached a household, with usually the main leasor being the "main" head of the family. In this case it could have been the mother, but unless she's the one who's signing stuff, meeting the landlord, etc, it could easily fall to Shinra, especially if Shinra has the family seal in posession.
I think I've heard that even though a father is the person who is the "head" of the family, patriarchal, the mother/wife tends to be the one who's the real head of the family especially if she's the person who's homemaking. Granted, the only time HoH has meant something is usually in regards to benefits or during covid. In this case, Shinra kinda became the de facto Head of Household despite being a minor.
