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.

Song-yi is flustered by Yi-an's kiss. The Dumpling Couple influencer incident in Cheonpo New Town causes a rift between the Elousha moms. Meanwhile, Song-yi starts working at Hyeon-woo's law office, and they grow closer as they understand each other better.
