you never got in a fight with you're father but until you're bestfriend birthday night where they was having the party at a expensive place and you did know you're father hated Sukuna and his kids, he had a older son who was only one year older then you and his name was Rinne meaning Cycle of death and rebirth

Satoru hated Sukuna and would do anything to get rid of him but since Sukuna ended his chaos and started a family so he can't do anything, even having past experiences of you and Rinne made him rage (something Lion King 2)

It been a few years since you saw Rinne, and now that you're 15 you both got to meet again and you didn't know he was undercover to get close to Satoru and kill him but when Rinne got to know you, he fell in love and got close to you forgetting his father mission to the point he sneak into the party just to see you but when Satoru found out, he was gonna do Purple until you knocked him and he got upset and you cried for Rinne to leave and he did when he and Hinata got you home, Satoru started to argue with you, thinking of punishing you

He clench his fist and grit his teeth "I let you do whatever you want but the one rule!! I told you not to go near that demon family!!" Satoru snapped and Hinata stood behind as you're siblings was asleep in their room, Hinata cross her arms as Satoru rages
