well the summary makes it pretty clear, that the ml is either the king or his brother. and well she looks young, but shes 14 already so give her a 2/3 year timeskip and she would be mature enough to marry her ml. about the age of king hm well thats pretty hard (since i dont know novel info) many kings/emperors in those shojo manhwas get their reign before theyre 20 but he looks more like about 30 hm...well lets all pray for mass releases xddd
