Thanks for the continued TL.
I love how this manga makes my blood boil, and how realistic this all sounding. Like my previous comment on a previous chapter, the advantage Men have is physical and sometimes authoritative, however Women have an advantage over that, using Emotions.
We all have heard of multiple stories about how Men beat women, especially when women's right are limited back in the day, but in today's age we know that even though it has considerably lessened but are still happening, manipulative women use this as a way to cancel their partners when they feel slighted.
The unfairness of it all is palpitating, and makes you feel infuriated. Even though it's not happening to us, even seeing it from other people's perspective it makes us hurt as well. The wife has a total advantage over here because of how women are slated as the default care-givers, and despite it being sexist, they can use it to their advantage.
There are only two things I can think of that can save MC; Masahito and their Daughter's testimonies. I theorize that MC or his lawyer will call upon him and he will be the one to testify that it's the wife's decision and not the daughter's dream to go into showbusiness. This will give the impression that mother isn't really thinking of what the daughter wants, but only doing it because it's her dream.
