A Mysterious Call This is all FANART for a Chinese variety show called "Who's the Murderer", all characters and settings are from season 4 episode 3. But I'll still give a synopsis of what happened that ep: "Three high school students are minding their own business in their favorite bookstore, when they suddenly get a call from people claiming to be from the future. They said that a murder has occurred in the book store 18 years into the future. Together they try to find out the truth of the murder."
