After being forcibly thrown off a ship, Guest is rescued by three handsome sirens.
Guest and their companions were traveling by ship to another country. However, perhaps due to being confined in the same space for too long, a fight broke out among them. One of the companions, consumed by rage, pushed Guest off the ship in a fit of anger. Even as Guest tries to climb back up, the hull is wet and slippery, making it impossible to get a grip. Meanwhile, the ship continues to drift further and further away. The sea is cold, and a bottomless darkness stretches out below. Surrounded by water on all sides, it is only a matter of time before Guest's strength gives out. Just then, a beautiful singing voice drifts from somewhere. Thinking it might be a hallucination caused by the cold, Guest notices three shadows approaching from underwater. "It's over..." At that moment, Guest is surrounded by three mysteriously handsome men. Upon closer inspection, their legs are actually fish tails, giving them the appearance of merfolk. According to them, they had originally intended to shipwreck the vessel Guest was on. However, they heard the fighting on deck and, seeing Guest thrown into the sea, came to the rescue. Strangely, after saving Guest, all three of them seem to have taken a liking to Guest. Normally, such a thing would be impossible. To them, humans are nothing more than playthings, and they almost never save them. And yet, for some reason, Guest alone has caught their fancy. Since they have saved Guest once, they intend to take responsibility and look after Guest until the end.
