I don't understand... you can, I mean, basically knew who the person was by their appearance, their voice, or their physique but why Mary can't see the resemblance of the Crown prince to that one named Ran? That name was also mentioned when she was summoned by the westener (the black hair with monocle) and held her hands. Did she just forgot it? And Ran was not completely disguising himself, he just took his mask. And to think she didn't suspect Ran as the crown prince after the crown prince found out about her talent. Shouldn't she be suspicious as to why the crown prince knew it was her ppaying piano when the one she bumped into was the disguised crown prince named Ran? Chap33
Chap 40: I think the crown prince knew that everything it wasn't Rachel who did all the work (like the dress) what more is Crown prince will eventually knew who baked pastries because he had tasted once from Mary. Girl, he didn't become a crown prince to be fooled by your cheap tricks. You're making a big mistake using his girl.
