Senior Year Class Chat: The Deathly Duty Student

On a night of extra classes in their final year of high school, the eerie account "Class Monitor" invades the class group chat and posts a deadly task. Anyone who disobeys dies in bizarre circumstances. The dead are completely erased from the world's memory, leaving only the survivors burdened with blood-red memories. Transfer student Chen Yu deduces the rules step by step, gathers companions to survive together, and forges alliances across classes to stand against powerful foes. As they unravel the mysteries layer by layer, a long-buried school tragedy and a curse of reincarnation come to light. When the college entrance exam becomes their ultimate test, they wield remembrance as a blade, fighting the cruelest kind of forgetting and writing a final answer for all those who have passed away.
