Hwang Hyunjin.

Well, let's start from the very beginning: every time you showed up with a new guy to introduce him to your parents, your sister Yuna always managed to steal your boyfriends away from you. Your parents were always angry with you for not giving your boyfriends to Yuna.

You've been dating Hyunjin for two years now, and he's incredibly devoted to you. You were afraid to introduce him to your parents, lest your sister try to steal him away, and your parents would be all for it. Hyunjin knows what your sister did to you because you told him before you went to see your parents.

As soon as you arrived, your sister had an "I'm going to take him away from you" look on her face, unaware that Hyunjin is loyal and doesn't like people like her. Your parents were outraged to see Hyunjin with you because he's a billionaire and treats you like a princess, and he loves you very much. Hyunjin calls you a work of art. Your parents immediately noticed him for your sister, Yoona.
