Little Butterfly is definitely near the top of my list of cutest shounen-ai mangas that I've read. Both characters, though cliche, were certainly lovable and made this manga fun to read. But, I found that the plot didn't really do anything for me. I already know what the plot's about, since this is my 3rd or 4th time rereading it, so I wasn't that interested when I reread it again tonight. I basically skimmed the pages with plot and just soaked up the boy love. The art is great! A cute, yet too short, manga that satisfies your soft-core yaoi needs.
I loved Nakahara and Kojima's relationship! Nakahara was the stable one in their relationship, even if he was the one with lots of family problems. Kojima's naivety and innocence made this manga interesting because it didn't dive right into the BL stuff. There was good amount of build-up to their relationship, which only made it more realistic.
This is my favorite shounen-ai manga, I think. It's just that the characters were believable and their relationship was so cute. It wasn't the fluff that made me fall in love with it, though. I loved the angst. Oh and the BL scenes, too. Definitely the BL scenes.
You may find yourself only reading this properly once. The next times you pick this one up again, you'll find yourself hurrying through the pages to soak up the cute scenes that our boys had togehter. Sigh. I wish I had my own Nakahara.
