Called it, Sensei is even further Shitsei than I thought he was.
What a fucking piece of shit. At least the mother of Haru can use the excuse that she's simply a scared, lonely and stupid kid. But her mom (well, shit, everyone in this manga that is a genuine mother has been flat out fucking awful thus far) and the Shitsei are just contemptuous asshats.
Personally I'm all for Momo and Haru just deciding to make their own life and happiness and for the rest of them to wallow in despair off panel.
