My personal list of shoujo mangas that I loved and piqued up my interest, even if I have to read (or reread) many of them.
Keep in mind these: = already read. = one of my faves. = yet to read.
Note¹: they're not in order most of the times, so just know that almost everyone of them is as valid as the others.
Note²: even if some mangas are still incomplete here, you'll be able to find a quick review since they've been already seralized in my country (Italy).
