At a rural school where he had transferred in a rush, Hyoun met Sunhong, who was cheerful and bright — the complete opposite of himself. As often happens with clumsy first love, Hyoun and Sunhong gradually became each other’s everything. Then, one day, Sunhong vanished like smoke. The brilliant first love of their eighteen-year-old days ended just like that. Ten years later, Sunhong meets Hyoun again, this time in place of someone else at a blind date… Hyoun, filled with betrayal and a thirst for revenge toward the woman who abandoned him, makes her an offer: "Have you thought about it? Ten million won for one night." We’re a complete mess now — can we ever love each other again?
