Overview:After being in a coma for two days, Tiandi finally woke up. After seeing her medical records, the doctor told Tiandi that she had fallen into a coma many years ago because of the same unknown reason. However, everything is the same as it was in the past, and no abnormalities can be detected at all. Tiandi recalled the moment she passed out, the red eyes she had seen, and how she had signed a patron saint agreement with the rain god because of this unknown disease. In order to ask the whole story of everything, before returning to Taipei, Tiandi found the grandma who abandoned her back then---Banai, she wanted her grandma as a priest to teach her how to summon gods... The God of Rain watched Tiandi's pain in order to escape the fate of death, and finally couldn't help telling Tiandi what would become of the world where the rain will no longer be in the future.
