Description

Also known as "I'll still sit on the main table after 800 times of persuasion"
Yan Xi wore a book, but she was still wearing the sister of the heroine who abused the book - a book that caused the male and female protagonists to be confused.
According to the abuse text, her as a drag bottle just needs to lie on the hospital bed and wait for the filming to be finished, while her sister needs to go through a bloody plot such as body abuse and heart abuse, Bai Yueguang's misunderstanding, and her escape from him.
Facing the body of Yan Xi, who was breathing wildly after walking a few steps, went downstairs and blew the wind into the ICU, was just going to make a fuss.
Until I saw my sister holding back her tears and stroking her hair over and over again, I said to her with guilt and heartache: Thank you for your hard work.
Yan Xi:...why is it worthy of the hero?
So Yan Xi dragged his seriously ill body and pulled his sister out of the mud again and again.
It can be called a medical miracle.
