What happens when the loveliest, kindhearted, beautiful mermaid has a crush on the on the human jerk?
Lucy is the Princess of Atlantis and her parents are Jude Heartfilia and Layla Heartfilia but sadly after her mother's death nothing was the same.
Her father would 'punish' her for her 'awful' actions which would leave markings. She had made the decision to runaway but one problem. SHE HAD A SCALY PINK FISH TAIL! Before she figured out her problem (Can't tell you how sorry. Have to read to find out) she has to get out of an arranged marriage. Can she do it?
