Is 'My Tsunade Senju' A Fanfic Or Original Novel?

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.

Awakening to a bewildering and astonishing reality, Seraphina found herself in an extraordinary situation: she had transmigrated into her own novel, stepping into the shoes of a character she had meticulously crafted. The male lead in her story was notoriously elusive, challenging to approach, and the master of a harem. Seraphina, now Zephyrine Everlynn, unexpectedly found herself among the women in his harem. It was utterly absurd! Promptly leaving the harem, Seraphina used her knowledge to help others win the male lead's heart, all for the right price. But why did the male lead continuously find his way back to her?

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?"

The day my elder sister stole my fiancé from me, I did not fight back. Instead, I slipped past the maid guarding me and went straight to find my father. “She can have my fiancé. I’m marrying the Regent!” My father stared at me in shock. Everyone knew the Regent was in charge, but rumors said he could not father a child and had a nasty temper. What they did not know was that I was born under heaven’s favor—blessed with the gift of life itself. In my previous life, that blessing became my curse. My elder sister and stepmother smeared my name, claiming that my curves and easy fortune meant I had been defiled before marriage. My fiancé was disgusted and turned away from me. That was when my sister seized the chance to take my place. Even on her wedding day, my sister was not at ease. She had me dragged away like a lowly servant and sent to a brothel, ordering the madam to torture me. While I lay dying in the dark, she lived in the light, bearing children with my former fiancé and enjoying a lifetime of happiness that should have been mine. Now that I had been given another life, I refused to bow to fate again. She might have stolen my fiancé, but she could never take the blessing I was born with.

I am dead. Only before my death do I realize that I am the sidekick in a tragic coming-of-age story, while my best friend Tinsley Wood is the female lead. I am destined to be disgraced and meet a miserable end, all to highlight her innocence, kindness, and endless good luck. When I open my eyes again, I am reborn on the very first day Tinsley asks me to take the blame for her.
