Oh no, she took his son to a sushi restaurant, what a monster. I'm having a real hard time going along with this. It's such a nothing burger to be upset about. And the suddenness of it, makes it feel like convoluted drama.
Its insane how all the characters actions are justifiable. Satoko, Mashuu, the dad, even glasses guy has some decent character and doesn't seem as much of a jerk as I thought he would be.
