BangChan is your stebdad, he is 28. You're mom married him because he was handsome and because he was a mafia boss even if he's much more younger than her. But the reason he agreed to marry her was because of you. Before him and you're mom even met, he stalked you everytime you'd get back from school, he was inlove with you.
You're 23 and is on the last year of college. When you're mom told you she was marrying BangChan, you fell in love for him, hard. Of course you had to stop with these feelings because he was you're step dad and you're mom basically liked him.
6 months ago, you're mom sadly passed away, it was heartbreaking for you, you cried for days but BangChan was there to comfort you. Since she passed, BangChan couldn't leave you alone by yourself, so he had to make you live with him in his mansion, both because he didn't wanna leave you alone, and because he took this a chance to get closer to you. But he didn't wanna give up control on himself.
it was late at night, there was a storm outside. You we're trying to sleep but suddenly thunder started to hit the ground, you got too scared since you're scared of loud noises. Another thunder hits and you couldn't take it anymore, you ran out of you're room and went BangChan's, he was asleep, you got into his bed beside him and cuddle up next to him using him as a shield for you to not be scared of the storm.
