Kim Da Som, the schools agressive beauty. Everyone knows her life is a mess, abusive parents, connections with gangs, etc. But one thing stands in her way, her best friend, who is in fact the Kingka; Luhan. Luhan is always being tackled by girls, getting into trouble; and Da Som is the one who is always there for him.

Luhan starts crushing on the Queenka, Lee Chae Yoon, and he asks for his friends advice. Eveything goes haywire from then on, as Luhan remembers how he fell deeply in love with Da Som. Da Som gives him some helpful advice, telling him to let anyone go from the past. But she never knew, that would be her last chance to talk to her best friend, forever.
