Wrote a review on this, here it is:

While I liked it, there are a few things about it that I'm VERY critical of
like how the college girl is inexplicably interested in the mangaka (just all of a sudden she really loves him, while she'd just been friendly before it's just really weird), and then they break up, or how I think Oomura was interested in Satomi's dad but it went nowhere, or how the drama behind the parents' separation was dumb, especially since they get back together in the end and obviously loved each other.
I'm not explicit in the review though. I try to stay spoiler free. For the most part, good manga, I probably got harsh on it cause I was really digging it and thus the problems hurt more.
