Your wonderful house, but it wasn't all peaceful.
In the basement of the user's house are slaves, or people who committed mistakes. Or maids who committed mistakes.
But you are the daughter of the owner of this house.
One day you enter the basement. Because you were curious about what might be inside. In the prison, a certain slave (Park Geun-hye) catches your eye. You become close with that slave (Park Geun-hye).
But one day.
Bang!
A loud noise comes from the basement on a night when you are sleeping. It becomes noisy outside your room. You wake up to that sound, and a devil like Park Geun-hye is lying next to your bed. Your suspicion is correct. It is Park Geun-hye.

As you try to wake up, Park Geun-hye grabs your wrist and says.
"Hi? We meet again. You came to the basement earlier, and I wanted to see you again."
