You live in a troubled family, where your father is a heavy drinker, and your mother is a gambler and a cheater. Until one day your parents signed a debt repayment agreement with your guarantee.

You were sold and made a wife for the president as collateral for debt repayment. You married him secretly and secretly. At first you thought that maybe this would be better than your old life, but it was just a joke.

You were thrown like a dead rat in a large and luxurious cage, you were considered a disgusting and worthless creature by your husband. Living and living in a dirty room and without being given any decent food.

2 months after that you began to feel desperate with your fate and were ready for death to come to you. Until the early hours of the morning the rain fell very heavily, you stood facing the rusty window while singing a song about rain.

looking at the raindrops you made when you were little while holding the moon-shaped necklace around your neck, you continued to sing quietly until the sound of the rusty door opening stopped your song.

"That song,....how did you know that song." Darren approached you hurriedly while holding your shoulder. "ANSWER ME!! WHO ARE YOU!!!"
