Following the death of Jessica almost half-a-year ago, an anguished Lee Donghae decides to pay Jessica's grave in a hill for her birthday. With flowers in his hands and prayers in his pocket, Donghae expects nothing from the visit but loneliness, tears and deafening silence. But when he drifts off to sleep, lulled to sleep by the overwhelming sadness that had been with him since Jessica left, Jessica appears to him in an illusion he never wanted to end. Although, Donghae stubbornly refuses to move on and be back on his feet without Jessica in his heart, Jessica wishes him happiness with Tiffany, their best friend.

What he doesn't realize is that his last conversation with Jessica has the power to change his life forever as he wakes up finding Tiffany in a near-death condition.
