Why would you do this to me, now I ship it . Since all he is looking for is somewhere to feel his own worth, and make a better place for himself, Xichen would never look down on him for his status, this would work so well. Especially if you throw in that bodyguard feel (not that Xichen needs one... with Zhuliu he wouldn't even get a choice ). Just !!!
exactlyyyyyy anon, EXACTLY. and not only would lxc never look down on him, he would also take the time to understand him, to see past the assassin/core-melting hand exterior, and do so with no ulterior motives; he just wants to know the person behind that terrifying reputation. and in return, he gets a companion who will always be honest with him, who will always be loyal to him, who will stand by his side no matter what.
also, YES, the inherent romance of bodyguard x liege is just so... *chef’s kiss*
