This is a story about "information gap" and "personality collapse". The heroine of a modern social animal travels through time and becomes the daughter of a criminal who ransacked her home. In order to survive in the capital, she rents out the dilapidated house left by her father. Unexpectedly, the tenant turned out to be the cold-faced chief assistant in the future who would cut him into pieces. The two began a life of frantic co-renting under the same roof, hiding each other's identities.
