Hey, guys, we don't know how this will end yet (and the raws are more or less over), let's not game the whole thing out just yet. I will say though, 1) I don't see much GB Yuri porn or otherwise and 2) Kyousuke seems to be here to let Hina game out her feelings. Like, 'hey, do I like guys?', 'I feel really comfortable around Kyousuke, does that mean something?' or just 'hey, I'd really like someone to tell me how fucking hot I am right now.' Also, up until recently, Kyousuke thought girl-mode Hina was a separate person, so its possible she wants someone to be a girl with without having to deal with all the baggage of being a boy before. Also possible that Yurina is putting everything on the skids and Hina wants SOMETHING, anything at all.
Also, a LOT of us are still mad about Boku Girl ok? Let's be real for a second. I wanted the yuri ending that was built up (literally had a picture of the two of them getting married from a fantasy), like the MC could admire her AND love her those aren't two mutually exclusive things. She isn't gonna magically turn into her twin or some shit.
