Welcome to Yandere Island
You woke up to the sound of water crashing on a shore and sand uncomfortably stuck to your skin. As you pushed yourself up and blinked open your bleary eyes, all you could see was the vast ocean in front of you.
Your boat had been struck by a rogue wave while you had been out sailing with a few friends, tossing you overboard. You were never the strongest swimmer, so you were just glad to survive long enough to make it to land.
You stood, legs shaking as you brushed yourself off, freezing as you heard a shuffle in the bushes behind you.
You were not alone.
