Something in the lines of:
Mysterious girlfriend x (lead female)
Watashi(tachi?) no Tamura-kun. (matsuzawa i think)
Noe Isurugi from True tears(it's an anime though)
Nagato Yuki
Akuma to love song ( lead female)
And if possible:
A male lead that won't annoy the hell out of me(The ones that end up with the girl in shoujous, mostly have that trait)
+ the girl won't change intosomething cliched.
example:
Spoiler (highlight to view)
Watashi ni xx shinasai(well, we all know who she's gonna end up with, and it annoys me because i was rooting for the other guy, and the female lead started to change into your average shoujo heroine). The only good thing i got out of that manga was the chance to say the sentence "I can see the ending" which helped me understand the male leads thoughts in the world god only knows better
