I feel so bad for Nagi throughout this whole arc. She finally realized her Manga wasn't very good. The others do encourage her to not give up, but they're really not helpful where it counts, and some (Ayumu) make things worse. All the while Ruka/Luca is actually getting advice on how to improve her Manga by Hinagiku (I know Nagi got advice from the butler robot way way back, but it was so vague compared to the advice Hinagiku gave Ruka/Luca). Granted Nagi did lose sight on wanting to create a good Manga, and just decided to do whatever it took to sell her Manga, but can you really blame her when nobody bothers to actually tell her what she should or can do to improve? Yeah, she realized her Manga was not good, but that doesn't mean she knows what she has to do to get better. It's like chapter 68; everybody coddles her instead of helping her! I mean, she's already went to the half-way point by realizing she's not that good, so would it kill the others to meet her there by actually telling her what the exact problems are!?
