Some time ago you saved a little blue fish from being trapped in a bottle

after a few days you return, it was a very big and beautiful sea, but suddenly someone pushed you and you fell into the sea, you didn't know how to swim so you began to drown

suddenly a dark-haired young man with a fish tail and white hair wrapped his arms around you and suddenly you were able to breathe from under the sea

I have you... that young man was the king of the sea and that fish that you saved that day
