tl;dr: A set of too many intertwining love stories with not enough time spent on any of them. The strange thing about this manga is that there were a number of stories that should be interesting, but that never really amount to much, and hence overall the manga felt quite shallow. There was obviously the main couple, who had issues with their relationship changing and how they would take part in that and that is quite interesting most of the time. However, this story pretty much reaches its end half way through, being followed not too long after by a sudden and pointless time skip, followed by arepeat of pretty much the exact same plot but with more fluff. Now, for the first half of this, the main story is supported by a number of side stories. There were the two distractions, Miyuki for Shirou and Miki for Momoka, but each of those just sort of fizzled out. Miyuki was a story about her seeming to be above love but falling in love anyway, but the ending for that was just really messy and didn't really feel like it was trying to do anything. Miki suddenly became about the true self verses the public self, but it was pretty much all talking in an info dump type fashion without any actual showing, and that too just sort of ended all of a sudden. In addition to these side romance stories focused around the main characters, each of Momoka's two friends also had their own romance stories, and Ruko's was genuinely interesting, but like the main story it ended half way through with the rest of her involvement being fluff. There was also the story of Shirou's sister Kei and marriage, but that only got touched upon at random points rather than feeling like an actual story. Hence, there were a lot of stories that seemed to have character and relationship development attached to them, but for the most part they all felt incredibly superficial and rushed. Now, it may well be possible to have all these stories in four volumes, but the manga spent way too much time on love scenes, and while the art overall was decent to good at times overall, the art for these scenes was more on the only decent side and the scenes themselves weren't that great and not worth how much space they took up considering how much the main stories needed more development, though it did make reading the manga super-fast.
