at least I feel the whole "I don't want to act like a kid" is legitimate considering how she even made a separate account to fund her habits. we could be so jaded, that we just see it negatively. like I know heroine that say "I don't want..." or "stop treating me like a kid" when they're literally incapable of doing anything without depending on someone else : fighting monsters, cooking food, getting dressed, etc. it's painful to read something like that.
I feel like dad's issue is going to be that because husband is so strong and up there in the world. there is going to be societal pressure but that is a minor problem, but it might be that because he is so talented that MC might die if the couple gets "too intimate"
