The third volume is undoubtedly the best. Finally, the two own up to their feelings - and Kurata actually comes out to his colleague and to his parents. This is actually a bit lighter overall, and the ending was really cute. Also, Tozaki wasn't as much of a pushover here. (Although that already got better in book 2.)
This series is a really enjoyable "gay-for-you" story, with likeable characters and a very nice overall feel to it.
