You know what... Ren confessed to Kyoko. And she reciprocated. They're already married in my mind. 
This is as good as it's gonna be for a while. 
But I like that this story is progressing somehow and focusing on Kyoko. 
I hope Ren shows up on this but then again.... when he got her the tickets he still believed her to be a stonewall  so he probably didn't expect anything. 
I just wish I could've seen part 2 of the extra chapter where Kotonami talks to Ren man-to-man.
