I can't bring myself to care at all for the mangaka-vs-editor storyline. It reminds me of a quip I heard once about how touring makes comedians' jokes eventually revolve around flying and hotels.
While this is a terrific point I and I totally get, it I'm still very much the opposite. I think this is a very interesting path and is so much of what this story has been about. The pointed questions from the editor really strike at the heart of Maekawa's problems. Shimizu trying to help her work through it is sweet and I like that Shimizu being her girlfriend doesn't automatically solve this issue as I feel other stories might imply.
Makekawa has, in fact, not told Shimizu she loves her. The score is two to zero now. Considering how much of a big deal she make out of not getting to close to the people she use to date, watching her make this next step is sure to be a lot of fun.
Not really related but I know what it's like to have a story you don't know how to finish. Add to this that's rare that I can't finish a story. (I'm not saying my stories are good but I can pretty much always finish them!) I tell myself I'm willing to tear it down and rebuilt it from the ground up as long as the spirit remains but I I'm not even sure what that spirit is suppose to be anymore. It went through several iterations over a decade and a half. And my ideas about stories were different at different times so . . . ugh. ^^;
