The Merman Trapped in My Lake, Vol, 1

Servaine Noxirel grew up hearing stories from her great-grandfather—tales of the grandeur their noble house once enjoyed and the madness and obsession that ran through the bloodline. But the strangest of them all was the story of his niece, a sickly young girl who owned a merman she cherished so deeply that she trapped him in a lake to keep him all to herself. Despite apparently bearing a striking resemblance to her and being named after her, Servaine dismisses this story about her great aunt as nothing more than a fairytale. That is, until she meets the merman who believes his Servaine finally came back for him after a hundred years. But has he been waiting all this time because of love? Or for revenge…?
