And so, he has a dream of becoming rich, thinking that there is no such thing as love, only money. He works hard his whole life while supporting himself and his sister through college. He works at a seafood wholesale market selling crabs to vendors. He lives with his aunt who has taken him and his sister in after their mother abandoned them.
With his big dreams and ambitions, he pretends to be rich while in school, in order to gain the attention of Hyun-soo, who is from a very rich family. Thus, he tries to get her to like him so he can marry into her family and become rich. But during this process, he falls in love with his Psychology teacher, Shin-young. He battles with his feelings and his ambitions, and ultimately picks love over money. Even though they go through hardships, he realizes that he can't survive without both, and so he gives up on Shin-young for money and wishes her happiness.

He thinks that if he has money, none of this would have ever happened. Through all the stress, he finds out that he has brain cancer and expresses his desire to die.
