Honestly, just a chapter to fulfill some fetishes : beating, "brat" correction, pissing...
It's far from the first time that they met someone who dissed the mc, and because the father is a down-to-earth man, asking him to correct his daughter would have been efficiënt enough.
PS : sorry guys/gals, but with so much people who thought this chapter "satisfying", it was nothing more than a specific kind of fan-service
