Cool is not suicide, but an accident. Eventually died of homicide. Perhaps out of pity, perhaps out of sympathy, Friends Sugiyaki also tried to help ghosts find their true identity and achieve liberation. Xia Gui is a high school student who met through the Internet. She is a friend, sunflower and cool. It is said that the ghost of a young woman, that is, the "summer ghost" in urban legend, will appear as long as fireworks are set off. Those "friends" who can't live the life they like can't find a place to live. The sunflower with a bright future is gone. All "cool" people have their own reasons to look at summer ghosts.
