Manga Like Mogui De Tiwen

Bei Yao is reborn back to 1996 as a cute four-year-old girl, and she goes to knock on her neighbor's door. Behind that door is the boy who will become an apocalyptic force in twenty years. Right now, the devilish Bei Chuan is only five, stuck with two crippled legs and self-conscious about his disability. When they reach seventeen, Bei Yao is the prettiest girl in school, while Bei Chuan clutches his wheelchair and sternly warns her "Stop saying that you like me, or else…" Bei Yao smiles sweetly and put her arms around his neck, and Bei Chuan can't help himself from hugging her to him, his emotions getting the better of him. Having been his lover for two lifetimes, Bei Yao just wants to feel the warmth of the devil for herself. Sensitive, insecure boy x Angelic, caring girl, in a doting romance between childhood friends!
