It a really light hearted story. The ML is stuck between his emotions and the NPC body emotions. The FL ignore that her sister was being treated like a commodity and she is the golden child as she would raise the NPC affection if they are nice to her. With her NPC sister backstory and her NPC parents calculating personality, it is hard for them to be nice to her.
Still despite admonish her NPC parents behaviour, the next day nothing happened to them and her NPC mother can still lecture to her and tell her not to embarrass the family. I dropped this after reading around 45 chapters.
