18 Again

At 37, Hong Dae-young feels as though the life he once imagined has slipped away. His promising basketball dreams are long behind him, his career is going nowhere, and his marriage to his first love, Jung Da-jung, is on the verge of ending. Then, in an impossible twist, Dae-young suddenly finds himself back in the 18-year-old body he had in high school—while his mind and memories remain those of a middle-aged husband and father. Taking on a new identity, he returns to high school and unexpectedly gets a closer look at the lives of his teenage children, discovering sides of them he never saw as their father. What begins as a seemingly miraculous second chance at youth gradually becomes an opportunity to reconsider the choices, sacrifices, and misunderstandings that shaped his family.
