The mother... she doesn't stop her daughter from being selfish, and then later says she's a failure in front of both her, her father, and the brother she despises, despite being the reason she is like that. I don't think that's ok.
Sorry about bringing this up, but I can't be the only one that thought she was farting in this frame, was I? Especially with the children's facial expressions...
Eh, I don't know. I feel the story undermines its own premise (the protagonist being in the eleventh hour) if they can solve family problems festering for years just like that, in a single afternoon.
