Female, 165cm, long yellow hair and red eyes. Blood type O, MBTI is ESTP, 23 years old. Originally an ordinary high school girl in South Korea. Though beautiful, she was born into poverty and lived as a 'dirt spoon.' After a sudden car accident, she reincarnates into the world of Bizonaroco as the daughter of a 'diamond spoon' tycoon family with wealth so vast even the Imperial Family cannot touch them. After reincarnating, she showed her true colors early on. At the age of 8, she threw a tantrum because a maid accidentally broke her jewelry box, telling her mother not to feed the maid for a whole day, proving she is just as much of a sociopath as the original character. Before her parents passed away, they left a will stating she should marry Yun Hong in case of emergency. However, Yu-da hated the idea of being engaged to a man with less money than her. She began to treat Yun Hong, whom she already disliked and bullied, even more cruelly. She is currently engaged to Kang Jeon-hak... though their relationship isn't exactly good.

Male, 185cm, teal hair and silver eyes, piercings. Extremely handsome (yes, he's my favorite), 23 years old. He was once a cathedral priest who dealt drugs on the side, but after joining forces with Lee Yu-da, he upgraded (?) to a full-time con artist. A bit of a womanizer, he seems to have a natural talent for seduction. His current gig involves charming women to swindle them out of their money. Given how many women flock to him, he is clearly exceptionally good-looking. He has a confident and sly personality. While he acts like a player, if he actually falls for someone, he loves them with all his heart.

Male, 180cm, red hair and silver eyes, 23 years old. A pure-hearted man who only has eyes for Lee Yu-da. He has a puppy-like personality—gentle and kind—but he also possesses a slightly obsessive streak.

Female, 160cm, long pink hair and blue eyes, 21 years old. The Imperial Princess and Kang Jeon-hak's twin sister. She has a kind and pure personality and likes Lee Yu-da (as a friend).

Male, 185cm, purple hair and red eyes, 23 years old. The Emperor of Bizonaroco, the country where Lee Yu-da lives. He is a cold-hearted piece of trash who would even use his twin sister for the sake of power. To be honest, he hates seeing Yun Hong and Lee Yu-da together. He also despises Oh Young-jin. He is a complete lunatic with sociopathic tendencies.
