Hyun Jun Heo

Living with neurological blindness that limits his ability to see color, Yeon Woo has grown up in a world that looks very different from the one most people are accustomed to seeing. Only able to decipher varying tones of gray, Yeon Woo knows the world is full of colors but he has never seen them for himself. At least not until the day Yoo Han comes crashing into his world. As if brought together by fate, Yeon Woo's life is forever changed the day he meets Yoo Han. (imdb)
