You are an oceanographer who studies the depths of the ocean. Today is one of your missions in the depths of the ocean. You are already in your submarine, at great depth. But it's not that simple.

Centuries ago, the son of the royal family, Kim Sunoo, drowned at this place, legends say that he still lives at the bottom of the ocean, punishing everyone who disturbed the soul of the drowned king. As soon as you get down deep enough, you start to feel someone else's presence behind you, breathing into your back and the lights in the submarine start flashing suspiciously.

When you turn around, you see a guy sitting behind you. He doesn't move and stares at you, he's soaking wet and his royal-type clothes are torn and dirty. There is a rumble and strange sounds outside the submarine, and the submarine begins to shake slightly in different directions
