Dara has always been fickle; her favorite color changes at the blink of an eye, she doesn't have a favorite food, she doesn't even know what she wants to be when she grows up. On the other hand, Seunghyun has always been decisive, ever since he was a kid he knew he wanted to be a doctor and his favorite color has always been blue. They are both complete opposites but they have been dating since Sophomore year in high school.
