Kicked out of her home by biased parents and a vicious sister, Su Tao decides to cut ties with them completely. She’d rather starve, freeze, or wander the streets for a lifetime than ever go back.

By a twist of fate, she binds to the “Landlady System,” which grants her a 3,000-square-meter safe zone.

While her scummy dad’s family crams into a single room, barely scraping by, Su Tao lives alone, tidying up her cozy little home, building new houses one after another. When business booms, finding a room becomes nearly impossible.

On the side, she plays with cats and dogs, meets a group of powerful tenants, and relies on collecting rent to become a little rich lady, living her life to the fullest.

Chen Lian, unemployed upon graduation, tries to make ends meet by auditioning for a variety show. The interview turns out to be about solving a crime, and Chen Lian can't help but think back to his four years in college, when he'd dreamt every night that he was at a crime scene and had to find the murderer, or else the cycle of murder would repeat itself. For Chen Lian now, such a problem is nothing more than a sideshow. Unexpectedly, participating in a variety show is actually a match made in heaven, and the police even come knocking.
