The Wind Blows

While Do-hun hides secrets from Su-jin, she considers an unorthodox idea to try and force him into a speedy divorce.

Brian Jeong and Son Ye-rim cook up a scenario for Su-jin's divorce project, and Do-hun spends time with his mother-in-law.

Moving her plan forward, Su-jin gets Do-hun to agree on a fishing trip with her. Brian stands up Ye-rim for dinner.

With his symptoms accelerating, Do-hun knows he must give Su-jin what she wants -- or risk her finding out about his illness.

Forgetting he needs to stay away, Do-hun heads to Kwon A-ram's kindergarten. Mun Kyeong-hun carves out a place in Su-jin's life.

Su-jin worries that Do-hun has reappeared to take A-ram away from her. Meanwhile, Brian and Ye-rim come across each other on a film set.

For the first time in years, Do-hun and Su-jin come face-to-face. Choe Hang-seo and Baek Su-a throw a wedding celebration. Brian meets Ye-rim's fiancé.

Do-hun's proposal for launching a sugar-free chocolate bar falls through. Su-jin locks herself away in her apartment, worrying her friends.

Jo Mi-kyeong and her mother disapprove, but Su-jin decides she wants to be by Do-hun's side -- and brings A-ram to him.

Do-hun remembers how he fell in love with Su-jin, who packs up his bags to take him back to the house. Ye-rim makes her choice about Brian.
