Synopsis

She transmigrated into a novel — but something went terribly wrong. Ten years too early, and waking up in prison of all places, a lawless jungle worse than anything she could have imagined. She survived by rolling with every punch, and a decade later she's clawed her way to the top of the cell block. Then an offer comes out of nowhere: her records wiped clean in exchange for one job. All she has to do is turn the newest inmate into the prison's top dog, and she walks free. There's just one catch — it's a men's prison. Disguised as a man, she takes on the mission, only to discover that her new target is none other than the male lead of the very novel she fell into. A story of an unflappable older woman and a dangerously fixated younger man, with tension to spare.
