Heart Voice Overheard: The Prince's Persona Crumbles - Season 1 (195 episodes)

Nan Xi accidentally transmigrates into an ancient romance novel as a cannon fodder of the same name who is about to be executed at the start. Bound to a merit system, she must accumulate merit points and exchange them for lifespan to survive. While mentally complaining on the execution grounds, her inner thoughts are unexpectedly overheard by the sickly Regent Prince, Li Qingmo, who rescues her on the spot. Armed with modern forensic knowledge, Nan Xi solves bizarre cases one after another, earning merit points by treating Li Qingmo's illness and investigating crimes, all while wildly complaining in her head about this all-powerful "crazy arch-villain."
