This trip takes her to Hakodate, Hokkaido, Japan. Yeo-reum embarks on her first-ever overseas trip. The excitement is fleeting, and as she busily follows the locations her clients have left behind, she repeatedly encounters a woman named Haruko at the same location. Haruko, who visits this place every year only on her birthday, seems to have something off about her. Through these seemingly coincidental encounters, Yeo-reum witnesses a shocking sight in Haruko...

Yeo-reum and Sang-sik were summoned by the chairwoman of a leading conglomerate. She was the sponsor of the "Day Trip" program that Yeo-reum was hosting. The chairwoman's request is simple: to ascend the Seongjeon Am Temple in Jinju, a place where you can achieve enlightenment if you climb ten times. Yeo-reum accepted Chairwoman Seong's offer, but in exchange for the generous fee, she stipulated the revival of "Day Trip." However, Yeo-reum began to harbor doubts. Why, of all people, had she asked her this favor? What other story lay hidden in this journey?
