On the first day of arriving in Tokyo, Hong and Jungo met like fate. The spring, summer, and fall of that year were beautiful times for both of them. Five years later, in South Korea, the two meet again by chance.

Hong keeps reiterating that his reunion with Jungo is nothing. Min-jun, who loves Hong, also senses her confusedness, but tries to ignore her and keep her usual self.

Jungo waited for her on Hong's daily run. Hong is surprised by Jungo's unexpected appearance, but he tries his best to ignore him. In three more days, Jungo will be back in Japan.

Min-jun eventually goes to Jungo's autograph hall and warns Jungo not to shake Hong anymore. Jungo's hope that maybe he can start over with her is slipping away again.

The night before Jungo returns to Japan, Hong calls him. Hesitated by Jungo's earnest request to meet and talk one last time, Hong ends up heading to his hotel.
