In 1975, Lin Wantang was reborn in the body of the real heiress who had been switched at birth. After activating the Happy Home System, she made her fortune selling braised meat, but then she met Lu Zheng, a “black-category” outcast living in a ruined temple. She was gentle on the surface but vengeful underneath; he was tough-talking, soft-hearted, and fiercely protective. From their first meeting over a “basket that's too new” to his words on the Great Wall, “I'll give you my ticket, and my life too,” she used her medical skills and the System to help clear his name, while he spent the rest of his life protecting her. Rebirth in a bygone era + System pocket dimension + real and fake heiresses + rugged man doting on his wife: this is a story about “I trust you, so I came.”
