He Has a Sickness that Needs to be Cured

Xi Ning is undergoing a punishment that involves being sent to various worlds to complete missions and fix plot-altering bugs. His assignments range from correcting the existence of characters absent in the original narrative to addressing supporting characters experiencing breakdowns or villains unexpectedly eliminating protagonists. As a consequence of his actions, Xi Ning is reborn into a series of challenging existences. These include an omega young master with anorexia, the emperor's son afflicted with skin hunger, a beautiful young vampire suffering from mania, a little mermaid with aphasia, and a forest elf battling depression. Fortunately, each world offers an "antidote" to alleviate his condition, a resource Xi Ning believes should be utilized. However, his pragmatic approach to these "tools" is disrupted when the plots unexpectedly twist. This leads to situations like a noble omega demanding a specific meal from a quiet, poor classmate, an immortal crown prince pleading for a comforting hug from a low-level demon, a dangerous vampire threatening a young man for a "bite," a speechless mermaid offering to sing for cake to interstellar pirates, and a depressed elf clinging to a dark magician, begging him not to leave.
