Choi Si-on

There is a serious problem with getting a job among young people in Korea. A young man in Korea named Doo-soo is lying to his parents while working at a market, because most Korean people don't want to a blue-collar job. But suddenly he has something important he has to do -- betting on Jang-gi (Korean chess). Would it be possible to change the world with a bet?

Jin-soo is satisfied with life and tries to make the best of things. When his father disapproves of the girl he likes, he is determined not to give up. However, his resolve is tested with the death of a former classmate and news that his love interest is planning to leave Korea.
