A group of close friends who attend a private school all have a debilitating crush on the sunny star pupil, Sun-ah. The only member of the group who claims not to is Jin-woo, but he ends up loving her as well.

Disillusioned with her work life, Mun-gyeong goes on a vacation to Mungyeong City on a whim. There, she and Ga-eun, a Buddhist nun who was taking travelling practice, rescue a stray dog, Gil-soon. The three unite and spend a night of emotional solidarity at an old lady's house.
