?Transmigrated as the Villain, I Let the Dragon King's Sister Share My Bed

At the start, I became a rich second-generation heir with a beautiful wife and a stunning school belle for a sister-in-law.
But Xu Mu couldn’t bring himself to rejoice.
The reason? He had transmigrated into the brainless villain of a novel—one who ab*sed his wife, forced the Dragon King’s sister to live in a doghouse, and ended up having his ashes scattered upon the Dragon King’s return.
Fortunately, Xu Mu awakened the “Justice System,” and he was determined to rewrite his doomed fate.
A wife should be cherished, and of course, his sister-in-law deserved to sleep in the villa’s cozy bed.
When the Dragon King finally returned, he was greeted by a loving and harmonious family.
Xu Mu soon realized that aside from the Dragon King, countless other protagonists began emerging—all targeting him—forcing him to fight back.
