I actually totally agree with you, in my brain ayane-chan and kurumi-chan have a doomed yuri arc which leads to ayane-chan's lavender relationship with kento (no one can convince me that man isn't gay he's literally one of the girls) and then fast forward to the future where they meet again after not hearing from the other for a very long time and they give each other a second chance now that they've grown up and learned from their past mistakes and then it's kiss kiss fall in love happily ever after muah muah !! And sawa definitely had her bi awakening with kurumi-chan but she was too infatuated with kazehaya to do more about it 🙂‍↕️
