i just wanted the story to end with Uta still identifies as lesbian, still loving another woman, whomever she ended up with in the end i'm fine just leaving it to author's decision.
i know bisexual exists, and i dont have anything against them, but when a story spends a bulks of its chapter focusing on same sex attraction, with no definitive hint of them being bisexual, in this case Uta never spend a second thinking about men, i fully expect them to follow through with it.
Changing her preferences without much of a build up is a disservice to the story it tries to set up, since Uta is the MC and we totally knows inside her mind that shes in love in Kaoru, and spend no time thinking of someone else. Konatsu on the other hand, already established as bisexual, as she derive pleasure from being different, so im fine with her character. Kuro, Miyabi havent had that much insight of their thought, so more chapter is needed, and Kaoru x Reichi we only see their outer personality without knowing what theyre thinking, so only conclusion we can see for now is they're straight because they're married.
