I moved into a billionaire's house as a housekeeper while hiding my criminal record.
But I wasn't the only one with a secret.

After being released from prison and living and sleeping in the backseat of a car for several weeks, my last chance finally came.
I ended up working as a housekeeper in a wealthy family.
Even though we had to live in a cramped attic with no windows to open and a door that could only be locked from the outside, it didn't matter.
My first job was to clean up the kitchen, which had been left in disarray by my hostess, Nina, who always wore only white.
This continued every day, but Nina seemed to have no memory of what she had done, and rumors spread that she was mentally ill.
Despite all the strange demands, I endured and worked hard to avoid being fired.
Then one day, a taciturn foreign gardener spoke to me with a serious expression.
I couldn't understand it, but when I looked it up later, I found out that it meant 'danger'.
Immediately after hearing that, I turned the handle to leave the attic, but suddenly the door wouldn't open.
"Have you locked me in my room? Let's calm down." They still don't know my secret.
Who I really am and what I can do… .
