Birkin says how much Haewon resembles her own daughter, Charlotte Gainsbourg, which pleases Haewon enormously. Haewon's mother is about to emigrate to Canada and stay with her brother, and asks Haewon about her future plans. Afterwards Haewon walks to Jongno Public Library, past Yoomyung-jang (lit. Hotel Famous) that has special memories for her. Later, in nearby Sajik Park, she meets her married ex-lover Lee Seong-joon (Lee Sun-gyun), a film director who is also her professor at college. They pass a restaurant, where they have already been spotted by his students, and decide to go in and have a meal with them. When Haewon is away from the table, the other students starts gossiping about how she is not pure Korean and comes from a wealthy family.
 
On March 27, Haewon and Seong-joon drive to Namhan Fortress (Korean: 남한산성) in Gwangju, Gyeonggi, where they get into an argument over how he broke up their relationship and how she had an affair with a fellow student, Jae-hong.
 
On April 3, Haewon falls asleep in the college library and dreams of a fellow student, Yoo-ran, asking whether she's having an affair with Seong-jun. And then, while strolling around West Village, Haewon bumps into Joong-won (Kim Eui-seong), a professor from San Diego, California, who divorced a year ago and is looking to re-marry someone like her. Later, while meeting her friend Yeon-joo (Ye Ji-won) and the latter's boyfriend Joong-sik (Yoo Jun-sang) at Namhan Fortress, she tells them about the meeting. And then Seong-joon calls her, demanding to meet immediately.
