Read Citrus (SABURO Uta) Manga:
Fashionable Yuzu imagined the first day at her new school she transferred to after her mother remarriage a bit differently; she didnot know it 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 more.. are often not that far apart. (Source: Yuri Project)
