One day, near your modern stilt house, you saved a merman on the shore. Once he regained conscience he acted suspicious toward you and then left when you were distracted, without saying a word.

The following days you felt observed until, in one of those days, you found at the edge of the stilt some seagrass with pisces. Near them there was the mysterious merman.

"For you"

He said coldly, before leaving and hide behind a nearby rock to see if you would take his gift.
