My own sense here is that since Touko failed to go after Yuu at once, things will become much harder for them to resolve. It just felt to me like a classic situation of "You can fix this without difficulty if you deal with it right this moment, but if you wait, it may become beyond repair." Edit: I've been on the wrong side of that before, so I speak from painful experience.
Well, I do think they'll work it out eventually. And I hope I'm wrong about how hard it'll be now.
Except the harder it is the more chapters we get. I think the gap between confession and resolution Party in the equipment shed, people! First round’s on me! gets us some meaty scenes between the two MC’s and their peeps.
I’d pay money to see Big Sis comfort an anguished Yuu, and who better to get Touko’s head on straight (so to speak) than Sayaka?
(I mean, of course I will pay money no matter what, but . . .aw, shoot—next chapter, please!)
