Sera was a poor girl living with a cruel father who was drowning in debt. One cold night, he sold her to a rich and mysterious man named Jungwon for a large sum of money.
Jungkook was a handsome young man who owned huge companies and a luxurious mansion, but he was very cold in his treatment of her. He took her to his mansion and provided her with a beautiful room and everything she needed, but he set one condition:
"Leaving the palace is forbidden."
She was afraid of him at first, especially since he silently observed everything, and if she disappeared for even a few minutes, he would start looking for her. He wasn't harsh with her, but he didn't show any obvious affection either.
As the days went by, she began to notice something strange…
Despite his coldness, he feared for her more than anyone else.
Once she tried to escape, but the guards brought her back to him. He looked at her for a long time, then said in a chillingly calm voice:
“It’s not safe for you outside… so stay here.”
From that moment she began to feel that his fear for her might be deeper than mere possession.
