So instead of asking if he's the one who introduced himself as "Mr. Angel", she asked something that sounded like a cheesy pick up line? And she didn't even clarify anything later? Does she enjoy making a fool out of herself? I can already see her regretting this later, when they arrange their marriage behind her back.
Also, why the hell didn't she know how he looks? Things like capture target's faces are always used to advertise the game, and she knows about him, so it's not like he was some hidden character.
