I loved, LOVE, this manga. I am willing to re-read it all over again in a near future. So it really is more a yaoi, but feels more like a shoujo, so the entire series is on that shelf. Kizuna is the one of the most adorable boy/girl ever, and no wonder Maki is so unsure about Kizuna's gender or about his own feelings. The entire manga is very cute, the characters are all awesome, and the end is completely sweet. Maki and Kizuna (such a lovely name! My favorite one besides Sakura) are one of my favorite couples.
I may re-rewrite my review once I finish re-reading all again.... which is going to be once the connection to Internet here gets better!
