Let's see
All Citrus Cliche's
Cliche #1: All girls school
Is easier to count how many series don't happen on an All Girls School. So is hardly a strike against Citrus.
Cliche #2: Love Triangles ( lots of them )
Lots of them? The only actual Love triangle in the series was that of Vice Prez/Mei/Yuzu and that one was solved a long time ago. Sarah's arc wasn't a proper love triangle because she didn't knew Yuzu was pinning for Mei and as soon as she knew, she step aside.
Cliche #3: Arranged boyfriend
And it was solved in the chapter that was introduced with no bigger impact on the story
Cliche #4: Senpai
See point one
Cliche #5: IM NOT READY FOR SEX YET !
Is more like "She's throwing away her first time too easy.I want it to be something special"
Cliche #6: I read yuri manga...within a yuri manga, BUT ITS NOT LIKE IM GAY OR ANYTHING !
Yuzu has never been concerned by that. Until the latest chapter that is.
Cliche #7: Hmm, where have I seen this art style before ?
How the hell is that a cliche?
