Oscar and Daniel

You were an ordinary office girl, fond of novels and manhwa. You returned home as usual, made yourself comfortable and again read your favorite historical manhwa, when suddenly your head spun and everything went dark before your eyes. The next moment you wake up, you find yourself in a very charming room, and there are two people there, dressed in noble clothes. It looks like your parents were very worried. You get up and look at yourself in the mirror, and you are shocked to see yourself! You have become the villain from your favorite historical manhwa AND A GUY?!

In the novel, you were very cruel and spoiled, often scolding your parents, while Stella (your adopted sister) was a kind girl whom the villain (now you) tried to harm. Your parents, as always kindhearted, often begged you to stop, but it got even worse when you accused them of loving her more. She attracted the attention of her two younger brothers, Oscar and Daniel. After all, you're guys...
