Task: Question Generation
Input (English): The main character Yong-ho (Sol Kyung-gu) in the first scene of the movie is seen dressed in a suit encountering what looks like a reunion party which is taking place on the banks of a river over which a railway bridge runs. He is in a state of extreme psychological trauma. He is then recognised by the reunion party group who try to calm him down and involve him to participate in singing some karaoke songs in order to get him to relax. Yong-ho behaves in a very disturbed way and this behaviour completely shocks the reunion group. He then makes his way onto the elevated railway bridge. One of the guys from the reunion party runs over to the railway bridge and pleads with him to come down. Yong-ho waits for the oncoming train and the moment before he is killed he screams the words 'I want to go back again'.The film then traces Yong Ho's life in reverse starting with the unfolding of the most recent events in his life prior to him committing suicide and then working back in time from there to the earlier stages of his young adult life.In the most immediate past Yong-ho is seen living in a makeshift house on the edge of a highwayand we learn how he arrived at this point by, among other things, losing money on the stock market, being ripped off by his business partner and being divorced from his wife. Here he is visited by an unknown man who asks him to visit this unknown man's terminally ill wife as this was her last request. This woman, we find out in time, was Yong-ho's true love years before, and who used to send him peppermints when Yong-ho was a soldier in the army.The movie takes us in rewind through Yong Ho's life from where he was a successful businessman, but philandering husband to a cheating wife, to where he was previously a brutal police officer and inconsiderate husband to a pregnant wife, to us seeing how, although he originally never really had it in him to be a brutal cop, but needed to be one and so, became one, to him spurning his true love and making sexual advances to another woman (which was to be his future wife), to him being a frightened and useless soldier, who gets shot and who unintentionally kills a female student during a military crackdown, to way back where he was a student who has aspirations for being a photographer and who has just met his true love (the future terminally ill woman), alongside that same river where he later meets up with the reunion party and where he decides to commit suicide.The film tracks the life path of how Yong-ho goes from youthful innocence, beauty and love to being a nasty, cruel and hateful man, and most especially self-hate, and this all depicted in reverse.
Output (English): Question: Who is the Main Character?, Answer: Yong-ho
