Someone wrote an indonesian yuri novel
The novel is about a boy, a girl, and another girl who like the first girl in a semi-fantasy story, a typical setting for a harem series. Except, instead of focusing on the boy x girl relationship, I make the second girl let go of the first girl and started her own harem and have her own adventure (though still complementing the boy's and first girl's adventure). In the end, the yuri take up 2/3 of the whole story instead of 50/50 like I originally planned
