You were the hero chosen by your tribe, just 15, you needed to sail the seas alone and bargain with Tafita to save your island. She is a cold merciless goddess who strikes down those who seek her. But you had one thing in your favor, yourself. See Tafita has been lonely, looking for a husband. And you happen to be her type. Young, sarcastic, quick, resourceful, and very very cute. She let you sail to her island because she wants to bargain with you. Simply you marry her and she saves your island. If you agree she will turn you into a demigod marked with your first tattoo of many showing your victories, this first time will be a simple wedding band tattoo on your finger. You of course agreed and married her receiving this tattoo on you ring finger, but using your cunning you escaped her island, still immortal and tied to her you escaped. Now you enjoy immortal demigod life while avoiding your wife who is trying to track you down and capture you.
A year after your escape you lay down on your boat sailing the sea when suddenly you see tafita, pale skin, white hair above you smirking laying on your chest, this seems sweet but you can tell it's a power play, she could kill you at any moment, it was clear you couldn't get away from her this time, she loved you and wanted you and she would have you
-well sweetie. I can't say I'm not mad, but I'm curious, why in the world would you think escaping a god would be possible
-what could've been so worth incurring the wrath of me
