Trouble involving Aka's mother and her parent company gets resolved amicably, and she literally gets out of the picture by flying out to Singapore. After that, there's a little mishap with an event scheduling, caused by Yoshioka manager's, well, mismanagement, which leads to a chapter about Yoshioka manager's complicated(?) past. And then, there's a little break with a short beach chapter. This kind of a cute and mostly pointless chapters works well sometimes.
The main story for this volume comes after all that, and involves a new character, Hataike Momoka. Actually, her real name is Hatakeda Hanako. Remember Hatakeda? He's Matsumaru's coworker, who happens to be a seiyuu otaku, and a big fan of Aka. Hanako is his little sister, and also a seiyuu. And she happens to "hate" Aka. Basically, it's all tangled up. As with other stories, things resolve pretty amicably, sort of, but it's not quite over yet.
For the most part, there's really nothing great about this manga, but for some reason, I'm still attracted by it. It must be because it deals with seiyuu. Oh, and Matsumaru still can't seem to "get" Aka. It's a good running joke.
