Her family used all their money for her extravagance and luxuries and brought a crisis of bankruptcy. While trying to figure out how to pay off their debts, she found a leaflet from the duke looking for a lost child. The reward is so much money that she could play and eat even after she payed off her debts! Following the memories of reading this book, right away, Lizelle picked up the boy who was caught in a trash dump in a poor village. She took the lost Lapel and went to the duke.

"This is the child the Duke is looking for."

Duke Chester said, looking at me with a doubtful glaze, "I need confirmation, so you should stay with my nephew in this house for the time being."

The strange cohabitation of the three people started like that. However, Lapel keeps thinking of her as a mother and won't let her leave.

"Let's get married."

Lizelle was startled by the unexpected words, "Are you insane? Did you drink?"

"One year. If you perform a contract marriage for one year, I will pay you ten times the amount of the rewards you were given."

"Can I call you 'honey'?"

And the contract marriage and marital life began. But why are his eyes constantly changing? Why do you keep coming every night!
