To He Yang, Shen Xiu Zhu is a cinnabar mole, his savior, and the white moonlight in his heart. Xu Cheng Yan, who has been in love with him for five years, is like an insignificant mosquito blood stain, like a substitute meal in the place of Shen Xiu Zhu, a replacement to fill the emptiness of his body. Then Xu Cheng Yan died in an accident, and He Yang waited, only to be met with a cold corpse. Realizing that the past five years together was too short, he wanted to turn back time, but desire didn’t help. Note: "Cinnabar mole" and "White moonlight" refers to those that can neither be obtained nor forgotten.
