XVT-014 - Adult film actress group date monitoring, Ryukawa Rio episode

As a fan, it's a well-made work. There are also works focusing on the other three, as well as those featuring Suehiro-san and Ozaki Erika-san, but I don't understand why Ryukawa Rio-san's came last. The content is also centered around Ryukawa Rio-san, so I want to give it a perfect score, but I also bought the works focusing on the other three, and it's disappointing that the ending is ultimately the same. It made me think the other two would be the same too. It would have been a better strategy to release each one individually and then add an hour of video bonus at the end. But since it's a collaboration work, I can't ask for more than that. I'd also like to see a documentary about these three actresses fighting over a man.
