Oh god, it seems don't know the difference between a shojo, shonen, magical girl, shonen ecchi ...!
I'm pretty sure that Nanoha, sailor moon, midori, suzuka, conan (seriously),... please go to wikipedia or a web
site specialized in japanime to get more intels but the main idea of a shojo is a manga made by girls and women for
girls and woman (but men can also be good writers).
Of course we are many guys to like that category but not every love story between a boy and a girl is a shojo.
To go back to the main topic:
-Bokura ga ita.
-Kare kano.
-Fruit Basket
-Lovely complex
-Itazura na kiss.
-Ayashi no Ceres.
