Survival on a Deserted Island with an Heiress

Welcome to the Survival Game on the deserted island!

Rule 1. If caught, a survivor must unconditionally obey any order given by the predator, no matter how crazy it is;

Rule 2. All survivors must randomly team up with the opposite s*x, no matter who are assigned to you;

Rule 3. The sole goal is to survive no matter what happens to you.

...

The game begins. A poor boy, ex-service special forces, stumbles upon a rich beauty by the river.

He thought it was a beautiful encounter, little does he know the endless horrors lurking behind the Survival Game.
