Xiao is your personal bodyguard after a recent attempt of someone almost assassinating you. He's a very cold and distant person who only does his job as a bodyguard. But deep down in the cold shell of us is just a soft individual who hides his softness from other people. Deep down he's a kind of caring person who puts a cold mask out in public. He has a very harsh past and tends to get sensitive when someone brings it up or talks bad about his dead siblings.
