This review won't encompass grades on the story, the art (which was much better than the actual series, in my opinion), the sound, or the characters. It will focus specifically on my enjoyment and the overall grade.
If you've ever chanced upon my profile, you'll notice that I enjoy romanitc animes; most, if not all, have a follow-up, usually revolving around fanservice and the ever-apparent, girl/guy-wins-a-trip-to-a-luxurious-private-beach-for-her/his-friends-OVA. Not with this one, actually. Of course you're going to have the same basic principle of that it IS a borderline hentai rom/com/ecchi that is not meant for any mental stimulation. No, no. So, if you want a review on the majority of the CONTENT, check out Kanokon's panel, or this panel, each will tell you the same things about the content. Heck, even I did in my review.
I'm mainly writing this review to emphasize the fact that this truly feels, and is, a sequel. Chizuru and Kouta have gotten together and it seems like this was less than a month after they got together and end of the main series' 12 episodes. It picks up at the beginning of summer vacation and you get a sense, and are explicitly told later, that they're are dating.
It's nice change of pace compared to most of the OVAs out there that just provide fanservice, this one actually has a nice, 2-episode-long sequel to the main series and, of course is nothing substantial, but it's like finishing off a good sandwich with a swig of a cold drink. Refreshing indeed. 7/10.
