Happiness (2007)

When stricken with a terminal disease, Young-su leaves his careless high life in the city, live-in girlfriend and dwindling business. He retreats to a sanatorium in the countryside in order to treat his illness, where he meets a young woman who is a resident patient there. Soon they develop feelings for each other and leave the sanatorium together to live in a small but cozy farm house. Their health improves dramatically but when Young-su’s friends from the city come for a visit, he starts to wonder if he should abandon mundane rural village and return to his former lifestyle.
