I would like to find some dramas where a not so famous/unpopular boy have a crush on a famous girl and he chases her or something. Like the girl does not like him at first and then eventually fall in love as soon as she will know him better :) It would not mind if it is not a High School drama but if there is it would be great!

Movie: Campus Confidential

Moments of 18 - not really unpopular male more like outsider since he is a transferee student

Extracurricular

Be My Boyfriend

in my opinion, both the reason FL on both drama fall in love as soon as she  know him better, in my country there's a wise man said "witing tresno jalaran soko kulino" -- meaning love grows out of habit

Same reason with ML in  Bring It On Ghost - love grows out of habit

That is interesting to hear :o

Maybe this: Abyss 

Or this: She Was Pretty   

I went thru my list of watched series and that's the only thing that somewhat fits your criteria. But this is all after they become adults, and fortunes have reversed in a sense, so the nerdy guy is no longer nerdy but a hot guy, and the pretty girl is no longer pretty just ordinary. But in both the guy had a crush on the girl in high school or growing up but the girl was not interested.
