After Xia Wei'an was killed in a car accident and Emperor Xingchen was in good health, Qin Shuang thought that she could finally relax and moved Qin Shanshan to the emperor's house in the name of taking care of her. In fact, she contacted the family.

Qin Shanshan is very attentive to Emperor Xingchen's affairs, ranging from dealing with official business to doing laundry and cooking. She is even willing to wash his feet with foot washing water everyday for emperor Xingchen. She works hard and has no complaints.

Qin Shuang sees it in her eyes and feels happy at the bottom of her heart. She only thinks that it's a good thing for her brother and sister to have a good relationship. For a moment, she feels that there is no regret in her life. But gradually, she finds something wrong.

Qin Shanshan's look at the emperor's stars is not the kind of simple and adoring look that a sister should have when she looks at her brother, but the sweet and shy look between lovers. Once she accidentally saw Qin Shanshan bury her head in those clothes when she was collecting the dry clothes for emperor's stars. Her face was greedy and enjoyable, which made her heart alarm.

So she began to observe Qin Shanshan. She cooked for emperor Xingchen herself. Breakfast, lunch and dinner were not the same. If emperor Xingchen didn't insist on eating by herself, she would even feed him with a spoon.

The clothes that emperor Xingchen changed were never used by others. Instead of using the washing machine, she rubbed them one by one with her hands. Even her clothes had to be washed. Not only that, she had to change the sheets and quilt covers in emperor Xingchen's room herself... This is not a normal attitude that a sister should have towards her brother.

When Qin Shanshan steals a kiss while the emperor is sleeping, Qin Shuang finally breaks out and asks Qin Shanshan to talk in her bedroom. She directly reveals her secret. Then she doesn't give her a chance to talk, so she strongly asks her to move out of the emperor's house and go back home!

Qin Shanshan naturally refused. This was the chance she had planned for so many years to get together with emperor Xingchen. How could they give up easily? So they had a fierce quarrel and even started to fight.

In this process, because Qin Shanshan didn't control her strength well, she pushed Qin Shuang down. Qin Shuang's head bumped against the edge of the tea table. Then she was paralyzed on the ground, and the hard marble edge was stained with bright red. Qin Shuang's back brain was constantly "gurgling" with blood. Qin Shanshan was surprised, and helped her to the hospital.

After some rescue, Qin Shuang's life was saved, but her lower limbs were paralyzed, her body could not move, and she could not even speak.

After three years in the hospital, she didn't get any better, so Qin Shanshan sent her to the best sanatorium and asked the best nurse to take care of her.

And to Emperor star there say is Qin frost oneself carelessly fall down, cause such result.

Emperor Xingchen's father died early, and his mother brought him up alone and never remarried. He knows this. Although he has no feelings with Qin Shuang, he is still filial. After he lost his memory of Xia Wei'an, he has no reason to hate Qin Shuang.

After Qin Shuang lives in the sanatorium, he comes to visit every three or five times, which makes Qin Shanshan suddenly have a good idea, that is to use Qin Shuang to promote him to be with emperor Xingchen!

So she found a chance to play a bitter drama when Emperor Xingchen came to see her. She made emperor Xingchen agree to get engaged with her under the pressure of filial piety. Although it seems to be a fake engagement, Qin Shanshan was serious. So one person planned the news, but only a few hours later, She spread the news of their engagement.
