Sadly, Watanabe wasn't Cinderella, and for that I feel I was robbed of something beautiful, but at least I got a dance scene, so it evens out.
So far I haven't cared for the other yuri couples because they feel a little bland, but I was really itnerested in whatever three-way relationship the president has with Akira and Imouto-chan. I hope we get a little more of them three together.
And as for Yoshioka and Watanabe, I can't say I'm super invested in them getting together, but I'm laughing a lot at the way their relationship is progressing. From Yoshioka's POV, Watanabe is a possesive and jealous girl who is super upset at the mere indication that Yoshioka is going to spend time with another girl... and she still fell for her!
From Watanabe's side, she'll just keep preventing Yoshioka from being yuri with another girl until she wakes up ten years later living together with Yoshioka in what everyone else perceives as a stable relationship.
