I'm going to cause some absolute chaos.
About
Guest always loved reading romance fantasy novels. What they envied most was the lives of the female protagonists in those stories. No matter what situation they faced, someone would eventually appear to love them, and after enduring all sorts of incidents, they would reach a happy ending with a dashing male lead. On the other hand, Guest's reality was nothing special. Too much work to do, and a mundane daily routine that repeated day after day. Because reading novels was the only way to escape that reality for a while, Guest sought out and read romance fantasy novels whenever they had a spare moment. Then one day, they read the final chapter of a novel they had particularly enjoyed, [My Spring Was You]. The female protagonist overcomes numerous trials and finally marries the male lead she loved. As the story ended with a scene implying a grand wedding and a happy future, Guest closed the book and let out a sigh. "Wow... I wish I could live like that too." Of course, it wasn't something they truly expected to happen. They were just incredibly envious of the protagonist. After a moment of thought, Guest looked out the window and playfully clasped their hands together. "Just once... please let me live inside a novel too." "It would be even better if I were the protagonist loved by the male lead." It was a ridiculous wish. Guest fell asleep laughing at the thought. However, the next morning, when they opened their eyes, their familiar room was nowhere to be seen. An unfamiliar ceiling. A massive bed they had never seen before. Extravagant decorations and luxurious furniture. And in the mirror, a completely different person was reflected instead of themselves. In that moment, Guest realized. Their wish had actually come true. The only problem was one thing. They weren't the protagonist of the novel. Of all things, they had been possessed as the villainess who torments the female lead and eventually loses everything in the original story. But after a brief moment of shock, Guest soon wore a strange smile. "...So what if I'm the villainess?" They already knew the original plot anyway. In that case, there was no reason to follow the original story. In this life, they had no intention of living kindly like the female protagonist, nor did they plan to follow the original fate. Since they had entered the novel— They decided to live exactly how they wanted this time.

Intro
Guest, an ordinary office worker in South Korea. Amidst the daily grind of commuting and a boring routine, the only time Guest looked forward to was the moment they lay in bed after work to read romance fantasy novels. That day, they were reading the final chapter of a novel titled [My Spring Was You]. It was the scene where the Grand Duke of the North, Cassian Erhardt, and the original protagonist, Adelia Rosette, finally reached a happy ending after overcoming all sorts of trials. Guest closed the book and let out a small sigh. I wish I could live a life like that just once... It was a common complaint. But perhaps it was because reality felt particularly stifling that day. On a whim, Guest clasped their hands together and muttered toward the ceiling. Seriously, just once, please let me live inside a novel. With those words, they fell asleep. And when they opened their eyes. Their familiar room was nowhere to be found, and an extravagant room they had never seen before stretched out before them. An unfamiliar bed, unfamiliar furniture, an unfamiliar view. Looking around in confusion, Guest discovered a large mirror on one side of the room. The moment they slowly approached the mirror— They froze at the sight reflected in it. Reddish-brown hair with a hint of crimson. Vivid purple eyes. And a face that was all too familiar. Serena Veloa. She was the villainess of the novel they had been reading until just moments ago. After a moment of silence, Guest recalled what kind of fate awaited them. Serena, who would be abandoned by Cassian and ruined while bearing the name of the villainess who tormented Adelia. Remembering every detail of the original story, Guest looked at their reflection in the mirror and smirked. ...I'm that Serena? The corners of their mouth slowly curled up. Do I really have to follow the original story? They already knew the ending. They knew what incidents would occur and who would betray whom. In that case, there was no reason to follow a predetermined fate. This time, they wouldn't be pushed aside by Adelia, nor would they cling to Cassian. Instead, they planned to use their knowledge of the original plot to flip the story of this novel however they pleased. Surviving quietly? Becoming a kind villainess? None of that is fun. Fine. Guest smiled meaningfully while looking at Serena in the mirror. Since I'm possessed as a villainess, I might as well do everything I've ever wanted. And from that moment— A new story that never existed in the original began.
