Jiang Yanran died, and Shen Yuchi went mad.
No one could believe that the aloof Mr. Shen would keep tormenting himself over a shameless woman.
White-moonlight trope, replacement trope, disfigurement and plastic surgery, and a groveling pursuit to win her back.
The heroine suffers in the first half; the hero suffers in the second.
Later, Jiang Yanran from another world transmigrates into a book and wakes up in the body of the original Jiang Yanran. The original heroine had loved the male lead deeply and spent years as his doormat for the sake of a man. The new heroine makes the male lead pay back in full for everything he did to the original heroine throughout the book.
