I'm surprised nobody asks what they're gonna do about sex now.
For me, that's the main question.
The one big problem with Nanase x Yuni, as it's been extensively discussed before, is that Nanase doesn't seem to have any desire towards Yuni's body. She's a teenager, full of raging hormones; she got herself a cute girlfriend; she should be desperate for time alone with Yuni, to hug her and touch her and kiss her and fuck her! But nope, all they have done for the last six months is exchange texts. Oh, and greet each other at school if per chance they meet. That's it. No weekend dates, no secret trysts, no quality time together, nothing. And Nanase was a-ok with this.
Now that they're back together, will Nanase suddenly find that she has a sex drive? Or is her idea of being a better girlfriend taking Yuni for strolls at the park and gifting her flowers and bonbons? And a sisterly kiss on the cheek from time to time?
