Qianxia’s friend, Jiamei, jumped off a building because of harassment at work, and Qianxia made a deal with a devil to take revenge for her. As she investigated her friend’s death, she found a hidden camera, learned about the indifference of Jiamei’s superior, and met an oddly friendly colleague. Slowly, the truth came to the surface. This is a tale of a fight between humans, but also a fight between the supernatural. But are the supernatural the true evil, or is it what lurks in the hearts of men?
