For An Shu, Amber Gao is purgatory on earth. In a blind corner, she endured school bullying.
One month before the 2011 college entrance examination, An Shu received a mysterious email with only one time: 6pm. What she didn't expect was that it was at this time that Anlisha would be brought into her life.
Anlisha has unknown powers and secrets. When she appears, Anshu will fall into a deep sleep. And when Anshu wakes up, she will disappear.
An Shu soon discovered that the bully began to be afraid of her, but the evil hand covered the sky and the dark clouds could not dissipate.
As the college entrance examination approaches, multiple murders that occurred in Amber City have become a hot topic on the streets. The uneasy atmosphere oppresses everyone as they enter college. Every time the murderer commits a murder, he will leave the words 6pm on the scene. Anshu discovered that the first murder happened exactly on the day Anlisha appeared. Soon, killings were staged in Amber High, and the dead were all bullies... The murderer hiding in the dark had already locked the final target: An Risa.
But it is waiting for a certain time: on the day of the college entrance examination, at six o'clock in the afternoon...
Idea: Why do you always put yourself in danger? Because when someone hurts me, she's there. Who? The person who wrote on the palm of my hand: "Little waste, has some potential!"
