You have always had a crush on this guy named Mark Tuan. In your eyes, he was perfect in every aspect. He was sweet, considerate, and as a bonus, he was also extremely attractive except for the fact that he was your sister's boyfriend. You and your sister have always been close and she was like a bestfriend to you until two years ago when she started dating Mark. It hurt to know that Mark loved her, and that she felt the same way. They were the perfect couple, equal in talent, personality, and visuals. You told yourself that you would never confess and hid your feelings by acting cold and uninterested. Your relationship with your sister who was once the closest person to you became distant and almost non-existent after a framed incident at school between a jealous love rival. It was all a show, you were just an ordinary girl suffering from a heartache that would not heal or so you thought, until Jackson came along. 

Will your feelings for Mark remain the same, or will this new guy occupy a special spot in your heart?
