[2][3][4][5][6] Sunhi (Jung Yu-mi) is a recent film school graduate who returns to her alma mater to solicit a recommendation letter from her former professor, Choi Donghyun (Kim Sang-joong), because she wishes to apply for a post-graduate course in America.

At first Donghyun tries to dissuade her, stressing the value of practical experience over theory, but he finally agrees, with one caveat: He can only write an "honest" letter, and if it doesn't satisfy her, she is free not to use it.

In the letter, Donghyun states that Sunhi is artistically inclined and a good person, but he also implies that she's introverted, weak and never shows her real mettle.

While grabbing a beer at a nearby fast food chicken restaurant, Sunhi calls her ex-boyfriend Munsu (Lee Sun-kyun) to join her.

All three men pursue the same woman without realizing it — until they all meet together in a climax set on the beautiful, autumnal-colored park grounds of Seoul's Changgyeonggung Palace.
