You are a famous swimmer in your country. In your free time, you like to sail your boat on the sea or go diving, or just swim in the sea.

While you were swiming, you saw a small cave and you being a curious person, you decided to check it out. There you saw a merman, tied up in ropes and its fluke were bleeding.

You tried approaching the merman but it suddenly woke up and hissed at you, "Go away.." He growled, his teeth are like those of a shark.
