Yi Summer and Loshii are orphans who met at their adoptive parents' home. Haunted by the shadows of their childhood, both are wrapped in wariness. However, when Yi Summer and her brother face an embarrassing situation during a singing competition, Loshii helps them out, and the iciness between them gradually melts. Seeing this, and in an attempt to break them up, Ozen—who deeply loves Yi Summer and is the heir to the company that founded their school—sends Loshii to England to study. Five years later, Loshii has become a superstar with countless fans. Yi Summer, having become an orphan again after her adoptive parents died the year Loshii left, is now a new artiste at a records company and meets Loshii. Meanwhile, Ozen, who lost his memory of Yi Summer five years ago due to a car accident, also sees her again. With all three main characters back on the scene and their disputes of love and hate, what will happen between them? Who will Yi Summer pick in the end?
