Which Anime Adapts Love Story Romance Novels Faithfully?

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.

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"

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...

At my graduation ceremony, I finally gathered the courage to confess my feelings to my longtime crush. But before I could, I was hit by a car. When I opened my eyes again, he was standing right in front of me with a frigid glare. "You're awake? Perfect. Then let's discuss our divorce." I blinked at him, completely dazed. Divorce? Wait—what? I hadn't even confessed yet. How on earth had this turned into a divorce?
