Elara: Sold at birth, is a servant to Alpha Draven. Elara was claimed and bitten by Alpha Draven at a young age and had her wolf removed from her. With no wolf and no power, she is stuck under his power and control. When an announcement comes out about Alpha Prime Darius looking for his Luna, Elara sneaks an entry in for herself. While hiding the fact that she is always claimed and bitten. Expecting to never hear of it again, she is shocked when the Alpha Prime Soldiers arrive to collect her. While Alpha Draven wishes to refuse and keep her, he's powerless and has to follow the order and let her leave. When Elara arrives at the castle, she finds herself standing among other potential Lunas and quickly realises that this competition was never intended to find Alpha Prime's true mate but the best candidate to be Luna. Without a wolf, she is sure she will be gone within the first round. However, she becomes shocked when she isn't sent home, but her being there is nothing more than publicity. Things become more tangled when Alpha Prime Draven chooses a Luna, and on the same day, Elara's wolf is returned to her.

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.

With the Duke on her side, the hidden clues about Lili's true identity slowly unveiled themselves, one secret at a time. And before the couple even knew it, the abyss had already dragged them into the true world of power and lies. A story of a possessive dragon duke and his mischievous flowery wife.

The next day I woke up, I am now the fiance of the Duke of Dubois Castle, or known as Lemon. “I am a demon who lives by desire and greed, you have yielded with the contract that you have exchanged with your life?” “Then what do you want?” “I want the whole of you Veta Le Blanchet, not just your blood, heart and soul, it is the whole of you.” Theroux Claude, the third prince of the kingdom. “Lady Le Blanchet, just how can you stand still this demon duke? If you ever get tired of him, you are always welcome to my palace.” Another troublesome man, my childhood friend when I was at the academy, Durand Gagnon. “I have attained this nickname not just because I follow all his Majesty’s order, but because I want to have a stronghold in the knight position so that I can support you my Lady, remember that my oath is only for you.” Then, what is my cousin thinking that he would say such things? “Sister, I have finally inherited the title of the Baron, please come back to our fief, and I will make sure to bring back the glory of our family!” As I try to relinquish the past, the more troublesome it becomes. Is clinging to the tiny bit of my life a wrong choice? And why is the temple spying on me? “Lady Le Blanchet is the only descendant of the family, you shouldn’t involve yourself farther with the Demon Duke.” “It’s done my Lady, as long as it is you, I can give everything, even if I destroy this Kingdom.” Hold on, just what on earth this demon wants from me?
