Pained

Pained (lit. "Pain") is a 2011 South Korean romantic melodrama film directed by Kwak Kyung-taek. Kwak's first feature in three years, it is a romantic melodrama set in Seoul, which is a departure from the director's previous Busan-based masculine thrillers and gangster movies. It is adapted from an original story by webtoon artist Kang Full.

Plot
Debt collector Nam-soon (Kwon Sang-woo) lost his sense of pain after a traumatic accident during his youth, and now regularly takes beatings for his job. Street vendor Dong-hyun (Jung Ryeo-won) suffers from severe hemophilia, a disorder that impedes the body's ability to stop bleeding. For Dong-hyun, even the most minor of injuries could be deadly. She's left homeless after Nam-soon collects the last of her money, so he decides to take her in. As the two grow closer, Nam-soon suddenly begins to lose his lifelong insensitivity to pain and the hurt of a lifetime washes over him. Together, these two lonely souls learn to hurt and hope again...
