Memo from the Vicious Supporting Girl

The day Song Qingning woke up, she found that she was living in a book. She is the white-flowered female protagonist in the book. She is destined to be heartbroken by the male protagonist and then go abroad sadly. She returns a few years later and has a happy ending with the male protagonist who pursues his wife. And the vicious female supporting character Ji Tingwan in the book will repeatedly provoke her, humiliate her, and make trouble for her - serving as the "catalyst" for the relationship between the male and female protagonists. Sure enough, Ji Tingwan stopped her coldly when they met for the first time: "Song Qingning, right? I remember you." Song Qingning was so scared that she closed her eyes. Then, Ji Tingwan stuffed a thermal bag into her arms: "Brown sugar water, ginger and milk to warm the baby. Isn't your period today?" Song Qingning: "...?" The second time, Ji Tingwan came to make trouble again: "Stay away from Fu Shichuan, otherwise -" Song Qingning thought she was going to have coffee poured on her. Ji Tingwan slapped a packed lunch on her table: "There are green peppers at the window in the cafeteria today. Don't you want to eat green peppers? I brought you some from another place." The third time, the fourth time, the fifth time... Ji Tingwan always came "looking for trouble" with a cold face, but remembered everything about her. She knew that Song Qingning didn't eat coriander, was allergic to peanuts, liked the window seat, was afraid of the dark, afraid of thunder, and had knee pain on rainy days. She knew about Song Qingning's birthday, the anniversary of her mother's death, and that she had a puppy that was lost when she was a child. She even knew when Song Qingning would get her period. Song Qingning gradually felt that something was wrong. The book says that this vicious female supporting character hates her the most. But—— "No one in this world has ever been so kind to me." Until one day, Song Qingning accidentally clicked on her memo.
