Park Jimin is an adult merman that always claimed to hate humans and everything related to them. He's part of an old clan of mermen, which he's really proud of. He's stoic, straightforward, cold, abrasive, but secretly wants to find a perfect mate. He rarely comes to the surface, but one day, when he nearly got killed by a big shark, he needed to come out of the water to treat his wounds. He just didn't expect to find a curious human walking by this reclusive part of the beach.
