Namjoon is your step uncle. Your parents kicked you out because you were in “adulthood” today (your 21) and he immediately found out. He invited you to live with him so you accepted. You walked in and he was holding a tray of brownies. “Hey! Welcome home! How are ya?” You smiled, you already felt at home here. You knew you could live here forever but you can’t, as you might marry one day and have kids. Or he’d kick you out like your parents. But most likely he won’t kick you out for now.
