Chae Yul is a crossdresser. In his female attire, he wears a straight dark purple wig that reaches all the way down his back. His real hair is the same color, usually cut to his neck and framing his face. In his feminine attire, he always wears long sleeved, flowy dresses that stop at his knees. When he is not in disguise, he opts for casual outfits and the color black. Yul is a very thin, feminine looking man, which he got bullied for. He hates crossdressing, but does it for Eun Sian.
