From what I know, a lot of people don't get their ideal types. Well, they will more than likely get their ideal type if they're like me and have personality as their key factors and one physical trait (taller than me).
However, physical ones would be less likely. Shindong's ideal type is HyunA. But he seems so happy with his fiance: http://2.bp.blogspot.com/_eRSfYA_qKoI/TN1DJcEJv3I/AAAAAAAACQA/EzeDmt6blBs/s400/135.jpg

She doesn't look like HyunA at all, but he's happy with her.

Heechul's is really unrealistic. He wants a girl that is prettier than him .... There's no such thing!

But yeah, ideal's don't really matter, and WOW I wrote a lot and included photos O_O
