A medical checkup reveals how much damage alcohol has done to their bodies, so Geum-ju, Hyun-joo, and Jung-soo decide to stop drinking right away. Ui-jun promises to grant Geum-ju's wishes if she manages to stay off alcohol for a week. But soon, a challenge emerges that puts Geum-ju's strong determination to the test.

Geum-ju loses sleep at night after Ui-jun confesses his old feelings to her. Seon-wook admits to Hyun-joo that he tried to bury his feelings, but he can't anymore. Geum-ju, Hyun-joo, and Jung-soo undergo withdrawal symptoms. Meanwhile, Gwang-ok says she's going to Seoul to take some time for herself, leaving her family surprised.

It's only now that Geum-ju's family comes to understand the true reason behind her broken engagement, and the truth leaves them filled with regret. With the townspeople, her family, and friends on her side, Geum-ju feels stronger than ever. Meanwhile, Geum-ju goes back to her job at the company.
