I went to bed last night without finishing this, frustrated and disappointed with the series. Then when I read the last section today, I liked it a lot more. I think that's probably because we shifted back to Satoru and Tamiya at the end, and they're just such a good couple. Satoru taking the initiative to confess to Tamiya under the cherry tree - a symbol that's supposed to make their love last forever - was really sweet, and I liked how well they communicated about their college worries, and the future of their relationship.
Again, Yu and Kagami's antagonistic, on-and-off-again relationship stands in such stark contrast. There are a lot of weird time skips with their relationship, too - I was annoyed because not only did we not get to see Yu's mother or his job again, apparently all that is over now? His mom's out of the hospital, he's back on regular student council duties (until they pass over the responsibilities to the next group), and he seems to have already quit his job. What was the point of introducing an interesting storyline like that just to drop it?
There's not really much of an indication that Yu and Kagami spend any time with each other outside of what we've seen on the page in these initial chapters - after the early Christmas party, where Yu gets angry because Kagami tricks him into spending the night, they don't seem to meet up again until after New Year's, when Kagami again finds a way to get Yu alone in his room. I liked that Yu started pushing back a lot more, expressing himself and telling Kagami why he was angry (a misunderstanding about Kagami studying abroad without telling him, and abandoning him), but this relationship still feels so one-sided.
Yu has his "oh! I'm in love with Kagami!" realization in this volume, but it doesn't really match with what's actually happening on the page. Why would he be in love with Kagami? What does he even like about the guy? Honestly, it seems like more of a temporary, mostly physical thing for the two of them, and I don't see that changing unless they start communicating a lot more. I find it frustrating that we just don't really get to see any of that.
They did have one good conversation where - like Satoru and Tamiya - they have to address what's going to happen after graduation, and whether they should try to attend the same universities. Yu, to his credit, absolutely refuses to let Kagami upend his life for a high school romance, and insists that he apply to his top choice university. I do like that when Satoru runs into them in a bookstore, on something that Yu refuses to admit is a date, Yu and Kagami seem more comfortable with each other, and have settled into a long distance relationship that's working out fairly well for them. (Yet another time skip, but at least this one had some decent content.)
I also thought it was interesting that Satoru rejects Kagami's frankly kind of terrible love advice: Satoru doesn't want jealousy in his relationship. Instead of using distance and jealousy to keep his boyfriend interested and to spice up their sex life, he chooses to just talk to Tamiya. Like I said in my review of the previous volume, I guess it's realistic for couples to have such different dynamics. What works for one couple might not be what's best for another, and I guess Yu seems happy enough, at least for now. Kagami really would make a good politician...he knows how to get exactly what he wants, and how to manipulate people. I just think Yu deserves better, and I'm a little sad about the story that he could've had.
I find it frustrating that we spent about 3 solid volumes of this (so far) 4 volume series focused on the "side" couple. Can you still call Satoru and Tamiya the mains when they're mostly comic relief in the background for 3/4 of the series? I wouldn't mind that so much if those three volumes had actually been spent developing Yu and Kagami's relationship, but somehow they had all these pages devoted to them, and I still barely feel like I know them or understand their relationship.
This is a decent, readable series that definitely isn't the best out there, but we'll see how the last couple volumes close things out.
