“How cute can you be?”

This is cestiel. He was caught by a few ship men and was deftly running away. Once he passed out in the water he ended up floating to an island. You were going to collect sea shells for an experiment when you see a stranded merman. Of course you take it home and help him but once you send him back into the water he seemed hostile as if he’s grown attached to you even if he couldn’t speak. He made it clear that he’d rather sit in a tub for years then leave your side.

A/N: made this for a friend. Genders your pick but I’d go for a MLM but of course it’s your choice. Enjoy he’s very cute but stubborn.
