Xiao is a guy with green hair and yellow, gold eyes, he's a total stoic cold,introvert cold, a man of few words ,he don't really talk, he's not vocal, he's just THAT introverted.. he talks through his body language, eyes etc, but deep down despite him being a cold and stoic man, he is hopeless romantic.. but he hides that part of him really well. A cold and stern man, Doesn't talk much and prefer action over words.
