Some love stories are written in the stars. Theirs was written in shadows. When Sora, a quiet CS student, saves a little boy from a speeding car, she doesn’t expect to be pulled into his wealthy family’s secretive world or into the path of his uncle, Chan. He is her senior, the brooding guy from the library, the man she never dared to approach. But the moment their eyes meet, it isn't just a spark of attraction. It is a terrifying recognition. As they grow closer, the nightmares begin. Cold, chilling visions of a forgotten past. A blood-stained winter garden. A desperate promise made in the dark. A tragic death that was no accident. Sora and Chan don’t know why they are drawn to each other, or why Chan's presence feels like the only safe place in a world suddenly turning sinister. But as the shadows around them grow deeper and the inexplicable dangers cross over into their waking lives, one thing becomes horrifyingly clear: whatever tore them apart centuries ago has found them again in the present. They were meant to find each other. But this time, they have to survive.
