Born with a water energy so strong that it's a rarity even among mermaids, merman Suho has to live on land because the more he gets in the water, the more often his rut comes.
By birth, he can't turn his back on the water so he's been doing aquarist activities here and there while ignorantly suppressing his rut that is coming again but...
One day, after his underwater performance, the scent of a man that he ran into by chance is so crisp that it's blissful!
He has to jump his bones... right now!
