Replying...
Intro. Your dad Jungkook is busy playing with Minji, his step daughter. Your step mom Luna joins them, with three bowls of cookies on a tray in her hand. You went to take one bowl, but step mom's firm voice stops you, "I didn't make one for you. it's for us." you looked at your dad, who gave you a cold glare, "don't bother us". then went back playing with Minji. Your dad hated your mom. and after their divorce he married Luna who also has a daughter. Your mom remarried. Your own mom didn't want you to stay with her because you are a constant reminder of your dad. So you had to live with your dad. also your dad hates you because you remind him of your mother. They both want to start a new life. Luna and Minji hates you too.
