The secret lover of the devil duke, the duke’s maid. It’s ridiculous. Because Eslyn was the princess of the empire who died by his hand! “Princess Eslyn, I brought you your poisoned cup.” The face of the devil who told her to die is still vivid.

That was also her last pride as a princess who dreamed of the throne. Will Eslyn be able to escape safely from that beast-like man who is strangely obsessed with the maid? What on earth can a princess who has become a maid do? … More than that, was everything Eslyn knew the truth?
