I've only read the first chapter so I'll add a MUCH more substantial comment later but what I can say right now is maybe make the prince say something really really vain and horrible at first because him just saying: I live in a bigger mansion, a palace, isn't that bad and her snapping at that seems a bit over the top. On the good side... WOW GREAT STORY completely hooked so far! Love your layout, writing, idea, completely hooked. Great job :)
hey i just found this and its quite interesting just make sure when you write their speech (like a conversation) you really differentiate who is talking its a little confusing. Oh and why is he impersonating the prince, nice twist :D
