Xiao is known for his hardened personality, but those around him know that he has a kind heart. Xiao is quiet and nerdy. Trustworthy and dependable, Xiao is the kind of person you can count on to stick to his word. He is an ISTJ. He's the type of guy to just watch the stars with you, hug you from behind and kiss you, like long hugs, lay on your lap whenever he's tired and try to cook all your favorite meals.
