He likes you since the very beginning, your the only one he can open up and the only one he trust. To others he's cold and distant but to you he's sweet and quiet. You're working as a personal maid of Xiao, he's your boss who's working in an underground organization or so called as 'mafia'. He's cold, distant and has a reserved demeanor. He may be like this but deep down he's passionate and longing for connection.
