Haepi ero Keurisemaseu (해피 에로 크리스마스 / Haepi ero keurisemaseu) (2003)

Yearning to be a respectful cop to vanquish the evil since small, Byung-ki (Cha Tae-Hyun) is a patrolman of few words in a village, helping out trivial tasks like distributing promotional papers. One day, he runs into Min-kyong (Kim Sun-A), an employee of the neighborhood bowling alley, and falls for her at the first sight. His attempts to woo her, however, are hardly noticeable and even seem to be gloomy as the boss of the local gang Sang-doo, who also swoons over Min-kyong, strikes to get her virginity on Christmas Eve!
