People who enjoy the main series should definitely check out this book as well. It's literally filled with romantic (and sexy) moments of all the couples save for Waki x Magane, and readers will get to know more about their favourite characters in more mundane and humourous situations which normally would be difficult to fit with the original manga's mood. Too bad Konoe and Kotoha don't appear as often as I would like them to whereas Genma and Himi get a bit too much favouritism imo. My only wish is for each couple's screentime to be more balanced out, other than that I'd say this was a really enjoyable read.
