This is one of the few shows that really ends the way I would like to see it end. It follows the characters all the way through to the end and I couldn't be happier. If you're looking for a show that takes the plot beyond the point where so many other shows like it stop, this is anime will become a favorite. If I hadn't known that the show has 25 episodes, I would've thought that it was going to end at episode 14.
It was also a nice change of pace because unlike so many other animes with romance, the guy wasn't the one who was head-over-heels for the girl. I don't know about you guys, but my experience with my boyfriend and the guys of my friends have dated, it's usually the girl who is more love-struck; so, this anime seemed just a tiny bit more realistic in that aspect. It didn't leave me thinking, "Why can't my boyfriend act like that with me?" This was a nice change.
Overall, Itazura na Kiss is just a great anime. It's very funny and very cute, with a very happy ending.
