Welcome to My Fiance is a Selkie (MFIAS) I hope you enjoy it, this series will be nsfw in the future! The intro was made more recently than some of the other pages because I realized most people don't know what selkies are or the mythology so this is a quick explanation.
LGBT 18+ NSFW
One day Conor, a human boy, met Selen, a selkie, and returned his coat to him. Selen vowed to marry Conor when they're old enough. Unfortunately Conor had to move away. They meet again over a decade later and Selen wants to keep their childhood promise and be together. Conor is having problems seeing his childhood friend in a romantic way. Can two beings that are different species from different worlds be together?
