Xiacheng was diagnosed with Schizophrenia and the splitting headache began to spread to his brain. There seemed to be a voice asking him: "Have you forgotten already? Think about it, XiaCheng...This is a very important thing..."; He had to go to the hospital for treatment and wanted to rely on drugs to escape the voice in his mind, but then he bumped into Shen Lin, a high-rank student from the same school that has Haunted him like a ghost and couldn't get rid of it-maybe he is the real "drug” to Xiacheng.
