Are There Any Spin-Off Mangas For The Improvement Book Franchise?

The protagonist of this novel is a complete bad girl, all because she believed that a bad man was her "fate mate" and wrongly trusted him and another despicable woman. This led to her family's ruin and the death of the man who loved her dearly. If given the chance to start over, she would no longer accept such a fate. She wants to cherish all the people who love her and seek revenge against her enemies. Just as she is on the brink of death, a miracle happens, and she is transported back four years. This time, she will not be toyed with like in her past life, and she will seek revenge in her own way. While she has enough tenderness and kindness for her relatives and friends, she has no mercy for her enemies. Anyone who has harmed her or deceived her in her past life will face her various forms of retaliation! Remember, she is a bad girl! Oh, and by the way, it would be nice to have a romantic relationship with Mr. CEO whom she let go in her previous life.

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

One moment I'm chasing after a rabbit and the next, I'm falling down a rabbit hole! What the heck?! This ain't Alice in Wonderland?! Though as I opened my eyes, I soon found out that I was no longer in my original body and that somehow I transmigrated into the light novel, A Fairytale Romance. And that isn't all, the character whose body I transmigrated into... is none other than the canon-fodder, stuck-up, arrogant, and selfish ojou-sama who was nothing more than a comic relief character, Maria Rosendrey. Life truly sucks...
