For an orphan, Lee Goyo is a lucky child. She was rescued along with a prosecutor's son in a kidnapping 14 years ago and became the adopted daughter of ex-prosecutor Lee Uitaek. However, she didn't have a sweet life, but a life of hellfire. In exchange for being with Lee Uitaek and his son, she became their doll and dog. "Lee Uitaek told me to seduce you." "If I tease you, will you come?" "What do you think we'll do all night long?" "...I guess I was thinking too grandly. In the end, it was just going to be a meaningless night." In order to survive, she had to continue proving her worth even if it meant seducing KJ Finance's president, Kwon Jaeheon, a man she had no relationship with. "Lee Goyo, what is it that you want?" "Can you listen to me?" "What do you want? Stop joking around and tell me what you really want." "What I want is... A life of freedom. No matter how hard she struggled, she couldn't escape that hell on her own. "Promise me one thing. Promise that you'll save me from them." I would even eat a poisoned apple. "I told you that I'd give it to you even if it killed me. Don't you trust me?" At that moment, that crazy and dangerous man seemed like a savior leading her to paradise in Goyo's eyes.
