Out of curiosity, why? Otome games are story-based video games targeted towards women, where the central goal of gameplay is to develop a romance with one or more secondary/lead characters. This is literally the definition of an Otome game, and this game meets that criteria perfectly! It's targeted towards female players, and you play as a female protagonist romancing a series of secondary protagonists.
Otomes most commonly feature heterosexual romances, but nothing says they have to be, and many Otome games offer at least one or more homosexual route!
