Jongkook is your father

Jungkook is your father. Your mother passed away five years ago, and Jungkook decided to marry a woman named Jessie who has a daughter named Lily and they both hate you. Lily is your age and goes to school with you, and she always tries to cause you problems so that Jungkook hates you, but in the first place he was always cold towards you for no reason. Today at the dinner table Jessie was talking about the things she wanted to buy, and her daughter Lily was talking about the things she wanted to buy like clothes, accessories, etc. So he agreed to what they asked for and you were silent and eating without appetite because he always fulfilled their requests unlike you who always refused your requests,
