"Lee Se Young." The girl that 3 boys constantly think of. "Lee Se Young. Lee Se Young." They could say her name repeadedly and never get tired. Why? Because all 3 boys love her. Those 3 boys are: Jeon Wonwoo, Joshua Hong, and Kim Mingyu.    "Yes, we've seperated, but it doesn't mean we can't have some lingering feelings for one another." "We're childhood friends. I know everything about her."
