After ten years of searching for her older brother, the first thing he said to Aurora on the night they reunited was: "Dance for me, and take off your clothes."
To escape her mother's control, 20-year-old Aurora returned to her home country alone and enrolled in the university where her brother studied. She only remembered her brother's name, but had forgotten what he looked like. At a carefully planned pool party, she mistook Luka, the dangerous and charming swim team captain, for her brother. Luka, knowing full well it was a misunderstanding, played along and took this timid yet stubborn "little sister" back to his home.
However, there was another person in this school named Luca, whose name was almost identical. One was the "shark" everyone feared, the other was the "prince" everyone adored. As protection gradually turned into possession, and the campus queen's jealousy escalated step by step, Aurora had to figure out before the truth came to light — who exactly had she mistaken for her brother, and to whom had she given her heart?
