Did people forget Moeko had the hots for Nanjou-senpai? Of course she'd get him, if she could. Still curious she could actually call on him like this, even though she claimed she 'burned those flags'. To be honest, I seriously hope in the months since he graduated, he actually did notice and accept his childhood friend's interest in him- she was pining hard. But even if she didn't get with him, this might still develop towards them ending up together properly, finally.
Anyway, yeah, we need to get Kanna Anjou laid romantically attached, else she'll probably never get how disruptive she is. I mean, there's probably other options, but a simple 'let her experience it, too' is straightforward enough for middle schoolers.
