Now not only does it turn out that the "prince" has to get married, but that if he marries the protagonist it would also be an excellent thing, for this he is looking for her. I honestly would have preferred the opposite. Right now everything that follows will not make the slightest sense, it will be all misunderstandings, the author is just trying to "stretch the broth". In a nutshell he is already in love with her and she with him, if they got married it would be a good thing, she cares little about the fact that the guy is the cause of the death of his parents, she is only afraid of being killed, unfounded fear because he is looking for her to marry her FROM THE BEGINNING. (Obviously everything is said when she is absent)
And now there are also rivals in love who obviously have no real hope of getting married but I suppose the author wants us to believe otherwise
if it turns out that he looks for her because he knew her as a child, the cliche of clichés. It can't be but never say "never"
