Bong-yong Kim is an unassuming Korean father who faces challenges at work, leaving him with little time for his family. He is overworked, as his boss treats him like a personal assistant, requiring him to drink late into the night and drive him home. His wife, Hwayeon, criticizes him for neglecting the family, and his teenage twins, Woo-joo and Dal-nim, also have a strained relationship with him. Only his youngest child, Byeol-nim, remains affectionate and endearing towards him. In “My Last Love,” the family eventually begins to show care and support for one another.
