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.
