Tasteless, unfunny trash with no payoff whatsoever. All of it is just the girls constantly interrupting Rio whenever he talks to Ichika and nothing else, the fact that they somehow don't notice him at all despite him literally standing in front of Ichika is beyond me. And that's not to say that Rio wasn't as annoying as the other characters, he's uncharacteristically spineless and pathetic in this doujinshi, which makes the experience even more miserable.
