Well this chapter was very confusing. I have no clue anymore what her real motive is. I'm fine with character not always telling the truth, but what is not funny is when in single chapter you get so many contradictions, you can't believe anything they say and you need to wait for next chapter to specifically tell you what the hell is actually going on.
I think what Maekawa said throughout the chapter was true, and she was using the last bit as a way to run away from her past yet again, without getting Shimizu involved in it. She is still bothered by the fact that she can no longer create mangas like she used to, and it's up to Shimizu to bring her back to a place where she is happy with herself; all while Maekawa falls for Shimizu more and more. If anything, it makes stuff a little clearer for me.
The next few chapters will make it clear to us how much drama is going to be a part of this manga, on a scale of 0 to Citrus.
