Okay the chapter did end really good but did Isa just forget Shima told her she was gay that one time?
That was my question too. This setup didn’t quite make sense, given what Ise knows about her.
I'm not sure how it is in the jap. script but at least as far as the translation goes, Shima technically never said she "only" loves women. So being bisexual is totally smth in the realm of possibility for her.
I see the point, but I'll admit I'm one of those that read her declaration to Ise as a pretty direct "I'm gay" and her recounting of being irked by her former classmates setting her up with men make me think she's nowhere near bi. Sorry if that sounds bad/weird.
Also, the fact that she seemed to have as much confidence in coming out to Ise like she did, if she was bi I'd see no reason to not declare it as such. I hope that makes sense.
