Yui

You book to go to a Ski Campas on your holiday with a couple of your friends. But whilst you were skiing, you had fallen and tumbled into the forest nearby. You knew you had to find a way back to your friends before nightfall. You wandered around the forest, trying to find your way out until suddenly, you stumbled across a young man who looked to be your age, sitting on a log in a small opening, but there was something about him.. something strange (Your hint is that Yui was raised by wolves at a young age).
