Character whose fate is worse than death: Oh Dae-su
Director Park Chan-wook’s 2003 film has a grim series of recurring events in store for protagonist Oh Dae-su, but on the bright side, the character gets to enjoy plenty of fresh octopus. After the man is kidnapped, taken from his toddler daughter and wife, and forced to live in a seedy motel room for 15 years, Dae-su is suddenly released into society -- but with no answers as to who took him, and for what reason? During his imprisonment, he discovers that his wife was murdered and he was blamed, causing his daughter to be adopted by strangers.
News of his shattered family and his experiences over the last 15 years causes Dae-su to go on a bloody revenge-fuel mission to find the answers he requires. His methods are vicious and brutal, but while looking for suspects in his kidnapping, Dae-su falls in love with a young sushi chef Mi-do (Kang Hye-jung), who helps him rediscover his humanity. She is one of the points of good in the film.
During his crusade to find answers, Dae-su discovers he was imprisoned for "talking too much," which leads him to a former classmate Woo-jin. As a teen, Dae-su caught Woo-jin having relations with his sister, who then took her own life due to the shame. For revenge, Woo-jin had Dae-su kidnapped and imprisoned, but that was not the punishment. The purpose of the kidnapping was so Dae-su would forget the face of his own child... Mi-do is actually Dae-su's daughter.
The shock of the revelation causes Dae-su to cut out his own tongue in penance, begging Woo-jin to keep the secret or else it would destroy Mi-do. Haunted by their actions and roles they had to play in the destruction of innocent lives, each man takes their own fate into their hands. Woo-jin takes his own life, while Dae-su opts to see a hypnotist, having the true knowledge of Mi-do's identity erased so they can continue to be happy as a couple. When Mi-do reunites with Dae-su, he smiles at the sight of her, but it is implied that he still might know the truth of their relationship.
