When he gets fired, and Da Jeong can't take it anymore, she files for divorce. This drastic step forces Dae Yeong to reflect on his life and all his regrets. Suddenly, he transforms into an eighteen-year-old with the same middle-aged mind. Renaming himself Ko U Yeong, he enrolls in his children's school, gaining a new perspective on life.
