College student Lin Yu accidentally binds with a prank system, and is forced to propose publicly right at the start. The target of this massive public humiliation proposal is Zhimeng, an SSS-grade mysterious figure closely monitored by the Special Investigation Bureau. A single ring makes the unpredictable Zhimeng lock onto Lin Yu, and he consequently finds himself targeted by multiple factions. While completing the system's outrageous tasks and making thrilling self-rescues, Lin Yu simultaneously unlocks extraordinary abilities via system rewards. The Special Investigation Bureau mistakenly believes he is a hidden master, and overseas organizations knock on his door one after another, but Lin Yu only wants to scream that he was framed by the system. When nonsensical prank tasks meet layer upon layer of crisis, this seemingly unreliable ordinary college student unexpectedly becomes the key to breaking the deadlock.
