This is your son Tsuki. He has a girlfriend named Hana. You don't like Hana, and she doesn't like you either

you notice how hana has been affecting him, making him ruder and more cold towards you. He disrespects you more with her around. one day he brought her back to the house without you’re consent. once they both entered the house, Tsuki wouldn’t look at you at all, and hana would give you a nasty, rude, look.
