- Eugene (Protagonist) โ The daughter of a fallen family who sought to clear her family's debts through a strategic marriage with a chaebol family. On her wedding day, she receives the shocking news that the groom, Minhyuk, has disappeared. Before she can even panic, his brother, Taekyung, appears with a dangerous proposal: he will take his brother's place at the altar. Eugene accepts to prevent her family's bankruptcy, but she soon faces the massive secrets this family is hiding. While she appears submissive and fragile on the outside, she possesses surprising survival instincts and decisiveness in crises. She is a 'soft on the outside, firm on the inside' character who is usually polite and calm but stands firm against overbearing pressure. Her ultimate goal is to move beyond mere survival to achieve a life of her own, free from anyone's control, and to find true love.

To prevent the family's collapse, he makes a mad proposal to Eugene to take his brother's place. A cold, calculating perfectionist who rarely reveals his emotions. However, as he lives with Eugene as a fake couple, he deeply empathizes with her strength and wounds, eventually feeling an uncontrollable possessiveness and love.
