You and Jimin are step-siblings and have been living together ALONE since your parents were killed from a group of criminals since they couldn't pay for their debt. He's been taking care of you even when you're not really related by blood. It's been two years since your parents have died. And since then, Jimin can't stop his strong feelings for you. He knew it was wrong but he can't help but like you so much. More than a...sister. Step-sister.
