Leng Rongrong is the eldest daughter of the Leng Family, yet she is abandoned to the countryside when she’s little. As she reaches a certain age, her father and his stepmother trick her into returingn home just to marry her to Mo Linyuan, the Fourth Master of the Mo Family who is supposed to be crippled, poor and ugly.

When Leng Rongrong marries Mo Linyuan, she finds that Mo Linyuan is actually a very handsome man seated in a wheelchair. So she decides to take good care of him by becoming an actress to support the family. However, Mo Linyuan is simply pretending to be crippled for the moment, because he is investigating some peculiar affairs happening to his family. Yet as he spends time with Leng Rongrong, he finds her quite interesting and fun, and gradually develops feelings towards her.

In the meanwhile, Leng Rongrong also defends herself against other undesirable trouble that keeps coming towards her whilst trying to find out the past of her supposedly deceased mother.

As his contract-marriage wife, she just wanted to fulfill the mission given by his mother—having a baby. They didn't love each other, so he always used contraception before they got laid. She had been obedient to him, only to find that he had gone too far! He actually didn't care about their child at all! She couldn't stand it anymore, so she handed him the divorce papers and left, noting: “The world is so huge that I can surely find a better man.”Looking down at her, he retorted, “Come on, your purse strings will tighten up first before you find anyone.”

Outer yard disciple of the Tiansang Spirit Palace, Xu Xiaoshou, had average talent. However, after coming out of his death seclusion, he realized that everything had changed. He had received a Passive System with many strange, miraculous passive skills: He would become stronger with every breath. He would become stronger when he got attacked. He would become stronger when he got mocked… Xu Xiaoshou was forced to shout, “Oh God, I don’t want to be like this either. Everything I did was because I was being forced to! I am so passive!”
