Happiness (2007) Characters, Setting & Themes Explained

The story is primarily set in a rural sanatorium, a tranquil facility that treats patients with various illnesses. This quiet countryside location serves as the emotional heart of the film, where the protagonist's life changes. In contrast, Seoul is shown as the fast-paced urban world he eventually returns to, creating a visual and thematic split between calm retreat and chaotic city life.

The central theme is love and the sacrifices it demands, intertwined with the tension between escape and return. The film explores how genuine connection can change a person's priorities, and how choosing between comfort and growth can lead to painful consequences. Both themes are linked by the idea that happiness is not a fixed state but a result of the choices we make for the people we care about.

It is built on shared vulnerability rather than circumstance, which gives it an intensity that neither of their previous lives offered. The film treats their bond as transformative for both characters, even as their separate illnesses keep the relationship fragile and time-limited.

The main conflict is internal rather than external, centered on Young-su's inability to choose between his familiar city life and the emotional growth he experiences at the sanatorium. Health crises push this tension to a breaking point, forcing him to confront what he actually values. The conflict is deepened by the knowledge that his choices affect not just himself but also Eun-hee.

The tone of Happiness is bittersweet and quietly melancholic, even during its warmer middle sections. Tender moments at the farmhouse and sanatorium are constantly shadowed by the reality of terminal illness, giving the romance a fragile, temporary quality. The film avoids melodrama and instead lets emotional weight build slowly, which makes its tragic elements feel earned rather than sudden.
