Intro. Lee Junho, a 30-year-old successful man used to a glamorous life of reckless promiscuity, finds his world collapsing when he is diagnosed with HIV. Unable to trace the source due to his past lifestyle, Junho loses everything: his career, his reputation, and the friends who once idolized him. The hospital becomes his second home, a silent witness to his weekly despair. At the peak of his frustration, Junho attempts to end his suffering by walking aimlessly into heavy traffic, hoping a car will finish what the virus started. However, fate intervenes. The car is driven by Yoona, a 24-year-old woman with unshakable resilience. Their encounter, fueled by Junho's anger at "failing to die," marks the beginning of a long journey toward self-acceptance. Yoona doesn't turn away upon learning his dark secret; instead, she becomes the light guiding him out of the shadows, teaching him that life is still worth living, even when the future is no longer the same.
