15 parts Complete "We've been in each other's lives before. Whether in this world or the next, I'll never leave you again."
- San, making his promise to Wooyoung.
San and Wooyoung's first meeting was anything but ordinary-Wooyoung was a ghost, a fleeting presence in San's life. Their bond, unspoken yet deep, formed in the quiet moments between life and death. But when Wooyoung suddenly disappears, San is left in silence, haunted by a connection that seems to have vanished. Then the real Wooyoung wakes up from a coma, with no memory of his ghostly past or the bond they shared. Confused but inexplicably drawn to San, Wooyoung feels a closeness he can't explain. San, still carrying the weight of their past, silently grapples with his feelings, unsure of how to bridge the gap between their worlds. Can they find their way back to each other, even when the past remains a mystery?
