Xia Cheng was diagnosed with Schizophrenia, and the symptoms of splitting headache began to spread to the brain. There seemed to be a voice asking him, "Have you forgotten? Xia Cheng, Think about it ... It 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.
