Either she gave her wrong ideal as a diversion.
Either she indeed gave her real ideal type but still fell in love with mc.
In both case, she dug her own grave.
Pretty realistic start.
You get old enough and you realize that just because you have a preferred type that doesn't mean those are the traits you end up falling for.
@RelM true, but at the same time, I don’t think that talking about your ideal type in front of the person you like who is completely different is a great idea.
