I agree with Nevri’s criticism of the story structure, but it’s worth pointing out that most of the sad past, marriage through obligation, etc. (i.e., all the non-Uta’s-unrequited-love stuff) was there from the very beginning or close to it.
So it’s not like the drama comes out of nowhere (as often happens when stories are desperate for some plot-twist energy), but more like the author started out with all those threads and then has developed them very sporadically and erratically.
It’s the abortive confrontations—the “let me ask you something—no, never mind,” the heart-to-heart talk interrupted by a phone call, the faked amnesia, and so forth—that really make me feel like the author doesn’t quite know what to do with the overall story.
And yeah, the way that confession business was handled is a real puzzler—I have no idea what structuring the reveal that way was supposed to accomplish.
