What is with these delicate, slow burn stories? Where is the passion? Women kiss, women FUCK. This pure love innocence uwu stuff in yuri manga is so cringe and so unrealistic. I mean goddamn they are married and sleeping in separate rooms, kurumi is always leaving ruriko alone, like how is she okay with that?? Zero intimacy, zero acting like a couple at all. I just feel like love between women is so misrepresented in manga sometimes, as if it’s somehow less than. Anyways, apologies, end of rant
In this case, it's because they're both painfully aware that they went into this as friends, not lovers, even though at least on one side the feelings were always there. We can quite well see that by now there's clear mutual love in this marriage, but it's harder to notice the slight changes when you're in it, especially when you keep focusing on not making things too awkward because you're, again, "just friends", even if it would actually not be a problem anymore.
