Hong and Jungo met each other like fate on Hong's first day in Tokyo. The spring, summer, and fall of that year were the most beautiful times for the two. Five years later, in Korea, the two meet again by chance.
The emotions that have been buried for the past five years shake Hong's heart. Jungo believes that fate made them meet again, but Hong wants to avoid that fate at all costs. The two start to struggle with each other's presence.
Hong keeps telling herself that meeting Jungo again was just nothing. Min-jun, who loves Hong, senses her confused feelings, but pretends not to notice and maintains his usual appearance.
Jungo waits for Hong on the road she runs every day. Hong is surprised by Jungo's unexpected appearance and tries to turn away from him. After three more days, Jungo is set to go back to Japan.
Min-jun visits Jungo's book signing and warns him not to trouble Hong any more. Jungo's hope that he may be able to start with her again is fades away.
Hong calls Jungo the night before he returns to Japan. After hesitating at Jungo's desperate request to meet and talk for the last time, Hong eventually agrees to meet.
