Stop Pretending to Be a Classmate, Your Vest Is Leaking!

Nankai High School, where students study late at night, has an undercurrent surging beneath the calm surface. The seven art students and music students are all members of the underground forces hiding under the skin of the campus. Lin Ruyu, who looks shy and timid, is actually a diplomat who accepts both black and white. He sets foot on campus to find his missing master; Zhao Wenbo, who usually likes to talk a lot, is the black technology commander of Wuying Organization, and he has deep hatred of being framed in his heart. The three major forces of Rebel Pavilion, Wuying and Mei are lurking in the same class. Tasks are released on the dark web, and masks are used to hide the true identity. Everyone carries unknown obsessions and secrets. The strange copy [Broken Mirror Rehearsal Hall] suddenly arrives, and the physical body is pulled in. The death of the copy means the death of reality. Broken mirrors in the room breed hallucinations, memories are infected, suspicions breed crazily, and former classmates are about to confront each other in the blink of an eye. A broken lacquered wood bookmark, a gold snake head pendant, a broken grain carving knife... Each of the keepsakes revealed clues. Some people are struggling to pursue the truth, some are struggling to survive with blood debts, and some are blinded by hatred. When layers of vests are torn apart, best friends at the same table turn out to be mortal enemies online. In the early stage, they fought against each other, and in the later stage, they had to put aside their grudges and fight side by side to fight against the final BOSS of the dungeon. "Classmate, stop pretending, your vest has been exposed a long time ago!"
