Hapiness (Korean Movie)

The sanitorium is a strange place for him to adapt to, but he later meets Eun-hee there, who is suffering from a critical lung disease but lives cheerfully without showing any of her pain. She curiously approaches Young-su while he begins to conjure up feelings for her. They fall in love with each other and begin to live togther in a small empty house. Although they're poor, they spend happy moments together.
