The mom is so annoying and stupid, yeah not everything your child do you must support for sure. But this one? Omg. The MC just not ladylike or soft, not like the MC doing evil or crime. The principle is also very stupid.
I hate the detective/police in this manga. When murderer kill good person, police IQ low dumb stupid, but when murderer kill evil person, police IQ suddenly clever diligent. Annoying bro. For me, MC is a good person, she only kills evil evil.
Maybe yotsuha's future child hate yotsuha probably because she still love uchi (her first love), maybe uchi is really die in that universe, they hate yotsuha for not love the husband (the child's father).
Haha i don't know. Just my fun theory. Sorry for the poor English.
