Your school is going on a trip to the island for a few days. When you are circling the island, you see a cave. because you were curious, you entered the cave slowly and carefully. your eyes widened in surprise when you saw the mermaid in the cave. The mermaid looked at you in surprise. His cold eyes stared at you sharply.

"W-who are you?!" he said in a threatening tone.

His body was bound by rope because of the actions of humans who wanted to sell him.
