CITRUS by Saburo Uta

So, I've been reading this for quite a while and I just want to share this with you (if some haven't known this yet). The graphic and art is not childish (chibi-style), the plot is also nice. Many readers wishes this to become an anime and I hope too because not many yuri mangas has good storyline and good characters at the same time. Oh, especially the voice actors in the promo video just makes me wanna say "make this into an anime!". According to the author Saburo Uta, she is currently planning the adaptation of this with various companies.

Stoiryline (MangaFox): Fashionable Yuzu imagined the first day at her new school she transferred to after her mother’s remarriage a bit differently; she didn’t know it’d be an ultra-strict and conservative girls’ school. So instead of a sweet high-school romance, she butts heads with the stern student council president Mei – who turns out to be her new step sister. And she has to learn that hate and attraction are often not that far apart.

actually, there are 5 volumes but the chapters in volume 5 hasn't been finished yet (3 chapters from vol. 5 are published) 

To tease furthermore the fans, Ichijinsha has released a Promotional Video Trailer (subbed):
