My Idol Can't Be That Cute

Mao Ziping has signed CDs, T-shirts, posters, and books, but he has never signed a ghost coin. The girl in front of him had a clean smile and a cute face. She handed over the Ming Coin and had an indispensable reason for him to sign: "The person sleeping here is your fan. Can you sign it? I want to burn it for her." On February 29, 2020, he was sitting in the nanny car. After a violent impact, a girl Wang Wen who was carrying his exclusive support card fell into a pool of blood and died on the spot. And a minute later, he traveled to the parallel world of February 28, 2021. That photo of Wang Wen did become the one buried in the cemetery now. But the cause of her death was that she was so happy that she died of a heart attack at his concert. So, who is the other girl Wang Zhongwen in front of him who asked him to sign the coin? Why are there only one word difference between her and the dead girl's names? A traveler from a parallel world like him? Or a deceased person with memories of rebirth? Can she find the key to get him back to the scene of the crash?
