What the Duke and Duchess Keep

Imperial knight Leticia Marionette is returning to the imperial capital after claiming victory on the battlefield when she ends up staying in the Duchy of Cetrian. The lord of the duchy, Lowell Cetrian, warmly welcomes her and her subordinates, but Leticia senses something suspicious hidden behind his kindness. She tries to report it to Belet, the emperor of the Empire and her master, but…! “So, Miss Leticia. Would you consider marrying me?” “Are you drunk?” Lowell stops her and makes her a new proposal. Leticia must stop Lowell’s rebellion and protect the lives of her subordinates. Lowell, on the other hand, must stop Leticia and carry out his rebellion as planned. Holding each other’s weaknesses in their hands, the two are left with no choice but to form a dangerous alliance through a contract marriage.
