Was there a romance novel where the male and female protagonists got together out of spite, and the female protagonist later found out that she fell in love with the male protagonist. In the end, she went backstage to see the male protagonist being intimate with someone else?

Yes, I recommend the game to you. This novel tells the story of two amnesiac big shots meeting in a game and gradually falling in love. It was a romantic youth-youth love novel, and the main couple was Thunder x Night. They kept touching the bottom line of the game, but every time, they could get points without getting hurt. The two of them lost their memories and gradually discovered each other's feelings through many encounters. I hope you like my recommendation.😗

I recommend " Supporting Female, Don't Run: Pick up the Corpse Husband and Bring It Home ". This book tells the story of the female protagonist accidentally transmigrating to become the supporting female character in the novel and later becoming a zombie pet. In her life, she found a zombie pet that looked more and more like a handsome man, and this pet turned out to be her lover! The male protagonist later turned into a zombie and lived with the female protagonist. The plot of this book is easy and interesting, and the pet elements are very rich. I hope you will like this fairy's recommendation.

I recommend "My Favorite Sweetheart: Black-bellied Boyfriend, Please Take This". The male and female protagonists of this novel met and developed a relationship in the infirmary. The male protagonist was gentle and considerate at first, but was later exposed to be a big black-bellied man, but he doted on the female protagonist endlessly. It was definitely a super sweet favorite novel! I hope you like this fairy's recommendation. Muah ~😗

😋According to your request, I recommend the book "Honor of Kings: Dear, Save Me Blue". Although it's not from the 90s, it's similar to the one you mentioned. This book was a gaming and e-sports novel. The female protagonist was also a useless girl who had been reborn. She met a national school hunk in the game. The two gradually fell in love through the game, and at the same time, a strong enemy descended. There were many details about Mobile Legends in the book. If you were a fan of the game, you would definitely like it. I hope my recommendation can meet your needs. If you like it, remember to tell me ~

😋I highly recommend the novel Addicted to Love You: A Different Kind of Bamboo Horse in Love. The male and female protagonists are childhood sweethearts in their youth. The female protagonist is a cold and arrogant scholar, and the male protagonist is a warm-hearted and arrogant boy. In the beginning, the male protagonist only thought that he only had a sibling relationship with the female protagonist, but later on, because of misunderstanding and emotional sublimation, they got together. This is a very sweet love story, it is worth reading. I hope you like my recommendation, Mwah ~😗
