I remember reading a manga about a yukuza coming to a woman to pick up her debts, only to start caring for her daughter who is being abused by her.
The yakuza dude offers to live together with the girl and severing his ties to the yakuza for her sake but she opts to stay with her mother....
I reallllllllly hope that doesnt happen here, Kanami-chan please go live with best onii-chan
