Icy Copper

All inhabitants of the Land of the Sun develop the power to shapeshift by the age of five—all except one. Still waiting for his powers even as a teenager, Copper spends every day searching for ways to awaken his abilities. But when his search leaves him stuck in a foreign, snow-covered land, he'll come to find that the world, and his destiny, are much bigger than he could have ever imagined. Source: Webtoon
