But Dam-deok’s sudden death leaves Seok-geun miserable and heartbroken. Bong-soo is the boring and prude husband of Seok-geun’s sister, Mi-young. His Italian restaurant business looks lackluster, and so is his marriage, until he meets Jenny, who later gets a job at Bong-soo’s restaurant.

Will these four people be able to get along with one another?
