Gokusen is gold so if you're gonna try anything for sure start there: http://www.mangago.zone/read-manga/gokusen/
For a classic golden shoujo I recommend http://www.mangago.zone/read-manga/hana_kimi/
All the characters are lovable specially the gay doctor (plus I love gender benders).
I've read a lot of shoujo since that's what I started reading. Is there anything specific you looking for? There's lighthearted ones, more serious ones, slice of life romantic, fantasy, etc. Otherwise, I'll just list a bunch of shoujo manga I like that have nothing to do with each other lol.
This is one of my favourites

Well lets see... since 8 years ago I always read yaoi and only sometimes (rare) another genre but now I need some change and came here hoping someone can suggest me a list or mangas that are really good between shoujo and josei. I already read some good ones but I want to find more if possible. Can anybody help me?
