Cute. Some light "pre-wedding jitters" (less than a chapter) but with the kind of quick and lovely resolution that I've come to expect from Shio-san. Now I wonder where they'll go from here.
Also, now that they've talked things out, they really ought to remove that rule about going back to being friends if they fall in love with someone else.
Glad they're finally on the same page, even though it took more work than it had to, but idiot couples have to be idiots I guess (mostly looking at you there Kurumi :P). I want many more chapters of them being a full on couple now, with no list of rules or pretends.
Man that confession felt like it took way too long and was dragging the story. The lack of communication was starting to kill me. Overall a pretty sweet confession, tho.
