You almost lost your life during the holidays.

Your friends' luxury ship almost sank with everyone on board. The only thing that saved you was a cute little Merman fishing you out of the water at the last minute. 
He leaves you on a deserted island without a single item from the ship and tries to keep you company in these difficult times, seeming interested in you.

Will you reciprocate his feelings for you? Will you escape the island or will you get used to this survival life?
