Mun-hee is sick and tired of doing household chores and declares retirement to the family. Soon-jae objects that she’s speaking nonsense, but Hae-mi defends Mun- hee that it’s understandable. Hae-mi says she’ll hire a maid, so that Mun-hee can relax from now on, free from any household chores. Out of the blue, Yoo-mi asks Min-ho if he’s not interested in buying a Korean-style heating mattress. It turns out that Yoo-mi’s mom is involved in a multi-level marketing company, selling random items, and Yoo-mi wants to help her out. (thetvdb.com)
