Jack (or Séan) is a merman. He has no experience with humans at all. He knows what they are, because of the old ancient history of his people, but he never saw a human in his entire life. He is very inquisitive and one day he gets caught in a fishing net. He stranded on the coast. Maybe it was fortune that he was saved by a young man with dark hair. But since Jack wants to learn everything about humans, he keeps the young man named Mark underwater in an air bubble ... maybe not the best decision.
