Ending Explained
In the conclusion of Park Chan-wook's "Oldboy," protagonist Oh Dae-su discovers the shocking truth behind his 15-year imprisonment. He learns that his captor, Lee Woo-jin, orchestrated the entire ordeal as revenge for a rumor Dae-su spread in high school, which led to the suicide of Woo-jin's sister. The ultimate twist reveals that Mi-do, the woman Dae-su has fallen in love with, is actually his daughter, manipulated by Woo-jin into an incestuous relationship as part of his elaborate revenge.
Devastated by the revelation, Dae-su begs Woo-jin to keep the secret from Mi-do, even going as far as cutting out his own tongue as a gesture of repentance. Woo-jin, satisfied with his revenge, seemingly relents and then commits suicide. In the aftermath, Dae-su seeks the help of a hypnotist to erase his memories of the incestuous relationship. The film ends ambiguously, with Dae-su and Mi-do reunited, but it remains unclear whether the hypnosis was successful, leaving the audience to ponder the true extent of Dae-su's liberation or continued torment.
