So damn cute.
Best part for me is Kyo going on the initiative with the hand-hold, here. Man has grown, by the time this will happen. What makes it even better is Anna just not giving a damn about washing her hand anymore now that they're joined like that.
Also, I assume this happens during the upcoming summer, in a couple to several months from current story time in the main chapters. They'd be considering themselves as dating at that point, even though they've totally been going on dates already.
