29-year-old Hwang Dae-woo (Park Yong-woo) is a successful university lecturer of English language, yet due to his awkward and shy nature around women, has yet to engage in any romantic relationship. When art major student Lee Mi-na (Choi Kang-hee (actress)) suddenly moves into his apartment complex, Dae-woo asks her out, and finds himself in an almost-too-good-to-be-true relationship. Yet, Mi-na seems to be hiding something sinister, and Dae-woo encounters a rather interesting twist to his fairy-tale-like first love.
