Spent the other comment talking about the manager character specifically, but... I want to talk about some of the other things that happened here. Like Anna being defensive about Kyo possibly being scouted by Yuki, it felt like. Clearly, she doesn't want to drag him into her line of work (maybe she understands it would be overwhelming for him, especially with how he's been for as long as she's known him?), but she's happy to have him observe it.
Also the editor asking about a girl he likes when she should realize the girl he likes is probably sitting right next to him feels like a completely unaware character. Like... they do know Anna is also a middle school kid, right? And this is probably her classmate that she brought on the site because they're close. The manager figured it out (Yuki made a good assumption, but jumping the gun a few months ahead of when they officially consider themselves as going out, I believe), but I will admit Yuki does seem to be one of those hyper-aware types.
Our first look at Nico. She's a funky character. And she seriously thinks Anna is really that cool and collected? To be fair, at work she's probably pretty good at presenting herself as such, but she's still such a child. Something Kyo willfully ignores every time he calls her mature and himself immature. He's more mature than he gives himself credit, but it's that lack of self-esteem that admittedly contributes to his childishness (not going to say it's the only thing, or the main thing, necessarily, but it does contribute significantly enough), while Anna's childishness comes from other traits.
Anyway, I know Nico shows up later for quite the drama defusal moment. I won't say more than that.
So yeah, the whole thing with show business and dating... I get the thing, I also get the reference BriGuy made about Rascal Does Not Dream. That wouldn't be a bad solution, really, especially if Anna stays a relatively minor celebrity as she is, instead of being as well-reknowned as Mai in the Rascal series, and the fact that her relationship with Sakuta ended up mostly unaffected, in the end, by the public revelation that she's dating someone seems like pretty good news for our cute pair here. A bit of chaos for a bit, but there's nothing wrong with a bit of chaos every now and then, and considering this story's track-record, it would be short-lived drama, if it causes drama.
