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.
