Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.

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...

A week before the college entrance exam, my twin brother, Tristan Doyle, runs away with a delinquent. Our parents abandon their massive corporate empire and set out to search for him. I intend to join the search, but a comment abruptly flashes across my vision. "Don't go, Ryan! If you skip the exam too, your family is doomed!" With no other choice, I shoulder the pressure and walk into the exam hall alone. Yet the moment the exams end, my parents return and lock me in the basement. Ten years later, I finally escape, only to discover that Tristan has stolen my identity. He's celebrated as that year's top scorer, gets a degree from a prestigious university, and is even married to my former high-achieving girlfriend, Alisha Hudson. They share a perfect life with two children. Furious, I attempt to confront them, but they bind me and throw me back into the basement. As I howl in rage, my parents reprimand me, "Tristan was never as smart as you, and that delinquent tricked him into running away. There was no way he could've gotten into college on his own." "You're his older brother. What's wrong with letting him have one thing? Stop being so selfish." I break down completely and die in despair. Only after my death do I learn that Tristan was the one who sent that comment. When I open my eyes again, I'm back on the day Tristan elopes with the delinquent. The comment appears once more. As I stand there frozen, Alisha gently nudges me with a smile. "Go study! Your whole family's counting on you."
