1: “The family are ungratefull tr*shes for selling the potions, and therefore their benefactor” (general impression of readers)
The mother was healed, and had no uses for some sort of tonic she didn’t really understand the use for, rather what was needed in their current situations was things like food, tools, maybe even clothes, all things wich she need money for. She even used some of that same food to offer a departure “feast” to her childrens.
There’s also 2: “he kept going back everyday bothering her!!! boooo!”
The dude, had his older brother and lover, dying of a dicease, so naturally he clinged on the only sliver of hope he had, the egoistical lazy tr*sh MC, and went to beg her everydays untill she accepted to help one “last” time (he even thanked her later and gave some food from the family’s food storage)
