Manga with older girl and younger guy or tough girl and innocent guy?

I want to know a manga with an older girl and younger guy. But I don't like it when the guy is like way to mature or perverted. They have to still be in school, (or if not then still have them be cute and innocent) and though I would prefer around 4+ difference, it can only be a one year difference as long as the age difference really shows. For example Boy&Cool, Misty Boy, Mou Speed de Karera wa, Ane-Mone Seikaten, and Himitsu Kichi were good. Dear Mine and Yoru Made Matenai are NOT what I am looking for. A manga with a tougher girl and innocent guy is good also. The guy absolutely cannot be perverted, or wanting to get under a girls clothes all the time. It's alright if the guy is perverted and then makes changes his ways for the girl he loves like Arata in Moe Kare (Takara can burn in hell). The girl CAN'T be all shy and let all the guys take advantage over her either. Examples: Lovely Complex, Special A (though I prefer the relationship to start sooner), Sukitte ii na yo, Ouran High School Host Club, high school debut, and monkey high. I'm NOT looking for: Kyou koi wa hajimemashite (nothing like any of her other works either), and NO LEADS like Amu Hinamori or Tohru Honda. Thank you~
