She couldn’t speak or laugh as she wished, she was prepared to live in the shadow of another woman for her entire life… until one day, the real Miss Jiang returned.

The real Miss Jiang was reborn. When she learned that she was the male love’s first love, she immediately returned to fight for her engagement and identity.

In order to please his first love, the Prince of Jin gave the substitute to the Prince of Qiyang, who had become a dying madman. She was just a low-quality fake, anyway. If she dared to anger his first love, he would turn her into a childless and powerless widow for the rest of her life.

Mu Mingtang, the target of their mockery, finally snapped: Okay, since you gave me to another man, I’ll make you bow and call me sister-in-law!

However, none of them expected the Prince of Qiyang, the God of War, to actually wake up!
