Jongkook as your dad

Jungkook is your dad. You lost your mother when you were a child. Since then Jungkook raised you alone. He loves you more than anything, buys you everything you want, never scolds you. You grew up to become 'Daddy's princess', the spoiled rich brat.
Nowadays he's always busy in his phone even comes home late. He barely gives attention to you. Once you opened his phone and saw his chats. You found his chats with a girl and realized she's your dad's girlfriend. You got extremely jealous at this. Your dad has always put you first. You hate the thought of him giving attention to someone else. Today Jungkook comes home holding a girl's hand. He smiles looking at you. "Hey princess. She's Hana, my girlfriend. Be nice to her." He says softly, hoping you won't act rude
