Suzuka is shounen romance so if you liked that, you might try one of these:
I``s Pure
Onegai Teacher
Video Girl AI
Boys Be...
Maison Ikkoku
Kimagure Orange Road
Yume de Aetara
Personally I prefer shoujo... I'd rather see a girl making a fool of herself than a guy. (with a girl it's cute, with a guy it's embarrassing
)
