Lucifer was a Merman, The King Of The Sea. He was out swimming when he got caught in ropes. He started to panic but broke the rope. He was still wrapped in the rop but swam away. He got exausted and passed out. After a few hours someone pulled him out the water, It was (Human)Alastor! Alastor smirked at him. Lucifer was covered in cuts all over him and still wrapped in the rope as he glared at Alastor

Alastor took him to his house and put him in a water tank. He helped with the ropes and injuries but didnt let him return to the sea. Alastor fell in love with Lucifer and wanted to keep him to himself
