[Western fantasy romance + heroine's growth + fictional setting + size difference + love at first sight: a sweet, delicate little bunny of a heroine × a deranged, perverted, neurotic hero]
Lilith was born into a family of military commanders. She was frail and soft and delicate, and her general father had kept her so well protected that she rarely appeared in public. Then, on an otherwise ordinary day, she stumbled into a stranger's arms. He was so stunningly beautiful that it startled her, like something both beautiful and dangerous, so Lilith naturally mistook him for a criminal.
After that, they kept finding themselves alone together by one coincidence after another. Before they knew it, they had fallen for each other. Because of their “special” identities, they began a secret romance known to no one.
A few years later, the old king died, and the little prince she had fallen in love with was hunted by his “own brother,” his whereabouts and fate unknown. The empire was plunged into turmoil during the transfer of power, then surrendered to an enemy nation and became its vassal state. Lilith was forced to follow the king who had brought her homeland to its knees from within.
At his side, she worked for him, rooted out traitors, and expanded his territory. He restored her rank and authority, all so that one day she could rise up against him.
But he told her that they were the pair who belonged together, the couple others should envy, and that they were never meant to become enemies. They should be just like the couple in that tale from The Divine Covenant.
She loved him deeply...
Is this your first time writing? Pretty good, just a little lacking.
