In that place he meets a mysterious man, Sun-jae and gets some advice from him. Thanks to Sun-jae, Hyun-min finally becomes brave and quits the job to start a business of his own which has been his vision for a long time. However, he loses contact with Sun-jae suddenly.

Seung-chul, a friend and a co-worker of Hyun-min and his girl friend Min-kyung help him to achieve the vision. Three years later, Hyun-min accomplishes everything he wanted but still feels empty. One day he goes to the bar to drink Windsor where he met Sun-jae the other day. He meets Young-ho who feels lost just like Hyun-min did three years ago. He shares his vision to Young-ho and encourages him to go forward. At the end by chance he realizes it was Sun-jae who was an anonymous investor three years ago and that is why he disappeared.
