What chapter does kei confess his love to hikari?

Awhh...what's the point of knowing? It spoils the whole storyy! =] Well, I'm not sure in the Anime, but in the Manga, you can sort of tell, because he tells her a few times, but since she's so thick headed she doesn't really understand "love..." *sigh* Anyways, it's in Volume 9! :D
