Coral is self-conscious about her rust-colored hair. Neither her family nor her childhood friends ever cared for her. To make matters worse, she was sold by her stepmother to a man living in the remote frontier. Her husband, Jade, is a marquis and head of the noble house that commands the dragon knights. Bound by a contract to continue his bloodline, Coral is required to welcome him into her bed each month.

"Even if you're scared, you can't stop me."

Although it began simply as a contract, Jade can no longer hide his growing affection for his devoted wife?!
