Lingxi knew that Shen Nian didn't love him, but he "had" someone he liked.
One day, she met Shen Nian's "him" at the house, a clean boy. Like Lingxi, he was Shen Nian's student.
"Hello, I am Chen Fang, a student of Professor Shen."
"Hello, I am Lingxi and I am also a student of Professor Shen."
Lingxi only wanted a family, and Shen Nian could give it to her, but she never thought that she would die on her wedding day.
God gave her a chance to come back. This time she would be herself and make them pay the price.
