A Princess's Fairytail-Bean x Mora

Bean lost everything; her home, her title, and those she cared for. Deciding to drink alone in the middle of the sea, she finds herself approached by a sea witch. The sea witch offers Bean a mermaid tail to be with Mora. Bean agrees, realizing she had forgotten all about her mermaid lover. Soon Bean finds out Mora is getting married and it's up to Bean to stop it.

Bean and Mora both belong to the series 'Disenchantment' made by the amazing Matt Groening.
