Btw MC's tests were poor so he couldn't get the college of his choice this lead to a fall out between his parents and divorce. Then Satsuki-sensei overhears he stopped coming to school and she didn't care blaming it on MC's lack of diligence for his studies until she also hears from fellow cram school students he always ranked high which unsettled her, she reviews her papers afterwards and realizes that poor performance wasn't of MC but some other student.
Man, that alone was awful and the fact she refused to let MC double check while he was crying made me lose any sympathy for her. She deserved, nah, she earned it.
