Suggest me something like Legal High or Densha Otoko. High priority to Legal High. New, old - anything. It just needs to be easy to find.

Hmm.. I'm not sure what aspect of similarity do you want to find..
But I would say

It's also about ugly man try to get pretty woman
Hero is quite similar to Legal High.
I agree with @Athenry HERO seemed to be similar to Legal High. (Good point is it stars Kimura Takuya :P)
