hello im looking for shoujo/josei with short male as the protagonist or love interest. he has to be worried about his height and dislikes how the girl is taller than him. younger male or same age is ok but i prefer if he's older than the girl.

thats it, thank you!!

Lovely Complex and Get Love!! - Field no Ouji-sama immediately come to mind; I read them both a long time ago, and thought they were pretty funny.

Meru Puri sorta works, but its shotacon-y...

The short male lead tag may be useful in finding other titles. I don't know how to limit the results to shoujo/josei, but there's only 9 pages so it should be easy enough to find something else that seems interesting.

I second Calamansi's recommendations and would add:

Male lead roughly the same age:
Haru x Kiyo
Fukumenkei Noise

Younger male lead:
Soredemo Sekai wa Utsukushii
