Rin wrote the following, "I like josei / shojo series that are not too romantic or smutty, my two favourites are Honey and Clover and NANA."
I could not have asked for a request more up my alley. I'm not recommending Ai Yazawa's Paradise Kiss because I assume everyone who reads NANA has also read that. On the other hand, I still want to mention the title because Paradise Kiss remains my absolute ideal of a series that nicely bridges the world of shojo and the world of josei.
And so I take this opportunity to recommend three titles that also function as excellent transitions from shojo to josei.
1. Venus in Love, by Yuki Nakaji, published by CMX.

She's about to discover that love can come with some unexpected competition.
2. Walkin' Butterfly, by Chihiro Tamaki, published by Aurora.
