A lot of people seem disappointed in this, and I get it since the ending was a bit abrupt, but overall I really liked this manga. Yeah the actual dating doesn't happen until the end and I would have liked to see more, but it doesn't bother me as much when their relationship starts off physically and they do go on dates or pseudo dates to the point that the confirmation at the end is beside the point.
I guess I just like Miko and Kyouko's dynamic enough that a lot of the flaws didn't matter as much to me.
