Song-yi goes to a motel to help Jin-ho but ends up getting entangled with Hyeon-woo again. At the English kindergarten's Father's Day event, cafe owner Yi-an joins in, and a sports day takes place amidst the competitive spirit of the kindergarten moms.

Song-yi, hoping to spark a new romance, joins a running club. She's surprised to find Hyeon-woo there, and on the way home from the after-run gathering, they mistake Ha-na's husband, Seong-tae, for an escaped convict. The three of them end up unexpectedly catching the real fugitive together.

Ha-na finds out about Seong-tae's cryptocurrency debt, prompting Song-yi to invite her for a temporary stay. Wanting to help, Song-yi arranges a counseling session for Ha-na with Hyeon-woo, the divorce attorney. While accompanying Ha-na to the session, Song-yi unexpectedly learns something about Hyeon-woo's past.
