After Ren Junchi met Yin Lu for the last time in the winter of his graduation, he made up his mind to abandon her and devote himself to a new life. However, when he was renting a house alone, he gradually realized that he had lost the most precious thing in his life.
After Yin Lu graduated, a phone call completely awakened Ren Junchi, but it was too late.
Ren Junchi returned to his hometown and went to Yinlu town to find her based on his vague memories. However, everything was like the snow in that winter, slowly melting into an unknown land and disappearing ever since.
