A might have a potential bug here. For the mom I don't get any of the level-up content if I level her beyond 50. I get the scene where she is crying on the couch, but none of the content that comes afterwards (like the scene where MC suggests her enjoying some 'quality' time next to him on the couch. Also, if I level up the mom, the level-up content for sister also will stop showing. So, if I don't pay any attention to the mom, I will get the level-up content where she chats with the friend, the ones where MC reads the chat, the one where sis wakes him up with the first surprise and the one where she wakes him up with the second surprise. After the second surprise, I get the picture where she changed her hair (why? God why? The old hair was way nicer). But then, if I do level mom, I get none of those scenes, except that I do get the picture with the changed haircut.
