Twin Dao Companions

The man who split the Demon King in two with a single sword can't even get the stove fire going when he comes home. Twenty-four-year-old Chu Ye has spent ten years pretending to be an ordinary person in a small town, all to live a peaceful life with Su Tang, the girl he grew up with and his unattainable first love. What he never expected was that another soul—a flirtatious, wild younger sister-in-law—also lives inside Su Tang's body.
