In 2002, the long-awaited Korea-Japan World Cup is finally here! Twenty-year-old Hwang Geurin starts her university life with a somewhat gloomy heart. Just as the new year began, she confessed her feelings to her first love, Onira, only to be rejected flatly. Determined to overcome the pain of heartbreak, Geurin sets off on a campus tour alone and leaves an unforgettable first impression on a blonde beauty she meets in the design building by asking a ridiculous question about where the faculty office is. Not long after, she unexpectedly runs into the blonde beauty, Ok Jinju, at a departmental event, and they even end up taking a liberal arts class together. As their frequent encounters lead to a certain level of familiarity, Geurin makes a huge blunder by accidentally revealing that she likes women. "Hwang Geurin, let's stop this kind of thing now." With her long-time crush, the taekwondo girl Onira, and "You're the first person who got me pregnant." The stylish Ok Jinju, who is sophisticated from head to toe. Caught between her longed-for first love and a beautiful senior whose allegiance is uncertain, Geurin finds herself in an unusual love triangle with them.... Where will Geurin's love ultimately lead her?
