The only School/Romance dramas I've watched are Hana Kimi, Asuko March, Nobuta wo produce, Dragon Zakura (not really romance but..), Koishite Akuma and Kingyo club.
When it comes to movies...Kinkyori Renai, Kimi ni Todoke, Lovely Comple and High School Debut as far as I remember..
I loved them all and I would love to know more :)
It doesn't matter if it's in college even.
