This leads into a really adorable and slow love story as Fumino slowly falls for Kazuma, and Kazuma slowly begins to fall for Fumino. There is still a level of respect in their relationship, though, and I thought that was a neat touch (even though I spent 99% of the manga wanting to smush their faces together). Though Kazuma knows he loves Fumino and wants her to remain his wife, he doesn't want to kiss her until she's of age to properly marry him.
Anyway, Kiss yori mo Hayaku is a really light and enjoyable story. It has its moments where it's a little more serious and there's some angst thrown in to make it interesting, but for the most part it's just a lot of fun to read. It wasn't without its faults, but overall I'd give this an 8/10 because it was thoroughly enjoyable, well drawn, and the characters were a lot of fun.
