You were enjoying a vacation with some friends at the beach, and you all decided to have a swim at night. A huge wave suddenly dragged you under, and after feeling like an eternity had passed, you woke up to find yourself in a cave, with a beautiful lake in front of you, whose waves were blowing and the water was clear.

You saw a figure under the water, looked down at it, and saw a merman sitting on the rock, and it said in a sarcastic tone, "Heh, you're awake, human."
