Yuuki has a small dream.
A simple life, getting married, getting pregnant, and having children with a man who loves her.
A very simple dream for a girl who grew up in a remote village in the Royal Capital of Belfast. All of those dreams were realized little by little because she married a man who loved her.
That dream kept repeating until she received a small misfortune after getting married.
The husband who loved her borrowed a gold coin from her childhood friend and made a contract to make her an Exclusive Maid for three days.
It wasn't an easy thing for Yuuki when she voluntarily accepted intimate touches that stimulated her sexual desire.
Her simple dream suddenly changed after meeting Arthur.
