On a cold night in late autumn, young Yu Cheng mechanically repeated the rituals of life for two people: ordering two cups of coffee in a cafe, whispering softly into the air, and filling the candy jar with his girlfriend's favorite flavor. Everyone knew the girl would never come back for another date.
But Yu Cheng stubbornly lives in the cracks of time. He would wait on the last subway platform until his whole body was covered with frost, he would chase a phantom that looked like a snow-clad figure on the street, and he would reunite with the lover in his memory in the coma after taking medicine. When close friends try to dispel the haze with mountain climbing and hot pot, and break the curse with the persuasion "people should look forward", those out-of-control fists, trembling medicine bottles and the empty last train at the subway station are tearing apart the truth cursed by the flower language of Platycodon - hopeless love will eventually turn into a guardian ghost, and those who indulge in memories are being swallowed by the past.
Until one snowy night, Yu Cheng, who had overdosed, held Xue Yi's hand again in his hallucination. In the crisp sound of the candy jar rolling down the edge of the bed, the sweet and bloody memories of the past are intertwined: the palms clasped under the street lamp, the scattered pages of the book, the lover who always stays on the "way home". When the boundary between reality and illusion completely dissolves, this obsession that spans life and death will finally have to make a choice between eternal protection and self-exile...
