This series kind of fizzled out in volume 4 for me, although there were a few bright spots in this conclusion. Was it worth the hassle of trying to track down a used copy of a hard-to-find book? Probably not, but it would've annoyed me to not know how it ended.
The actual conclusion is volume 13, the first section of this omnibus. It wraps up with Yoh going to college and Haruna joining him there a year later, after she agonized through the difficulties of a long-distance relationship and insisted that she fully supported him following her dreams.
We also finally get Haruna meeting...well, not Yoh's parents, because his dad is still oddly never around, but she does get an extended, combative face-to-face with his mother. Who it turns out is a lot like Asami, so you can guess how well that went. I wonder if that means Yoh is like his dad...because his mom and his sister are kind of unbearably self-centered, and he is weirdly such a sweetheart.
The funniest thing about this whole series is that Yoh turns out to have been the world's worst romance coach. Haruna chose him because he was handsome and popular and seemed like he knew what he was doing. But he absolutely did not at any point in the narrative. Everything he "coached" Haruna on just...made her more appealing to him, really, and not to any other guys she was trying to attract. Because Yoh has very little experience with romance himself.
The reality is that he's only popular because he's hot and aloof, which makes him seem cool. But he's not intentionally like that...he just doesn't speak to people because he's really shy and easily embarrassed.
My favorite part of this omnibus was the side story in Tokyo, with Yoh's friends back home worrying about whether he was going to make any new friends in college...and Yoh forming a very unexpected and accidental bond with the second-hottest guy in school, who initially hates him.
That whole sequence absolutely cracked me up. The guy was just stewing about how badly he was wanting to win this whole competition that Yoh had no idea he was even in. And then when he sticks up for Yoh (to impress girls) and invites him to karaoke (to impress girls), he ends up actually talking to Yoh and finding out what a genuinely nice, quiet, loyal guy he is. With a girlfriend who...doesn't fit the idealized image at all, but whose pictures Yoh smiles at and gets possessive over, like anyone would ever want to steal Haruna from him.
There is another side plot with a guy who forms a pigtail-pulling relationship with Haruna at school, then eventually confesses to her. Kind of unnecessary, but I guess it's nice to show that she does have options beyond Yoh, and chooses him simply because she loves him. I did like that she full-on lectured this guy about how to NOT speak to or interact with girls he's interested in, because he did an absolutely terrible job of everything.
The stupidest part, though, was this dude ripping up Haruna's college recommendation...and that being a thing that somehow damaged her chances at getting into college? Why...why wouldn't the school just...print out a new copy...?
These are the kinds of absurd twists that got thrown in just to drag out drama, and I did find that element of the storytelling pretty frustrating.
Volume 14 was a "spin off" showing more of the year that Yoh and Haruna spent apart, with Haruna working hard to ensure she could end up at the same school as Yoh, and Yoh displaying absolute steadfast dedication to her. They're sweet, although Haruna's over-the-top personality and constant shouting was starting to get on my nerves after a while. I get that Yoh likes her passionate nature, but can't they ever just have normal conversations? At a regular volume? Without her passing out and landing in the hospital because he kissed her?
The side characters got massively sidelined in the last couple volumes. Asaoka and Mami barely got any lines. Asami, annoyingly, got a whole side story in Volume 15. It was a bit unfair, honestly, for her coworker to be presented as such a terrible girl - kind of Asami in a different hat. Because some of what she was saying in the beginning, about Fumi being way too good for Asami, was true. At least she did eventually admit (to herself) that she's very much in love with him, and I liked that she defended Fumi when the girl got spiteful after his rejection.
The final story was just completely unrelated, so I don't get why it was included in this series at all? It was way, way more in line with Kawahara's other big series, My Love Story!!, with a delicate, pretty girl falling in love with a big burly traditionally unattractive dude.
I guess that's her thing? Haruna was supposed to be "unattractive" with an extremely hot boyfriend, although she's actually very pretty the entire way through. She's just outspoken and athletic.
Anyway, I liked this series more at the beginning, but it was a fun enough read. Even if the conclusion didn't feel all that satisfying, the side story with Yoh at college almost made it worth it.
