I can understand the tension the author is trying to put on the story, and the fact that everything is getting put on the table with such subtlety is amazing.
Now I have to wonder what IS happening next chapter. They did jump straight into December, so either we get to stew in Aya trying not to regret being an useless lesbian that can't communicate, or if Mitsuki's thick-headedness will recede enough that she can catch at least a whiff of the issue brewing up.
If they jump us into the prom, THANK GOD because the angst has been choking my life slowly these last few chapters and I want some release, but if they don't I can only hope they don't turn it up too high.
