The female protagonist is reborn as a death row prisoner instead of the legitimate daughter of a famous family. She has a very low starting point and relies on secret letters in prison and prison-breaking wisdom to gain power; the male protagonist is a "crazy proton critic" who pretends to be a playboy, but is actually the leader of the secret intelligence line. The two of them used their humble bodies to turn the world around. Unique mechanisms such as prison lantern messages, lamp wick clips, prison clothing acupuncture, Taishi's pseudo-calendar, and disaster reports advance the plot, with equal emphasis on excitement and reversal. Testing each other → breaking out of prison side by side → two-way redemption, emotional advancement and deep connection with the major case line.
