I wanted this manga as soon as I found out that it had been published in English. Having read some scanlations of it a while back, I knew that it was heartwarming and cute and in its way, quite original too.
You see, here, the uke might be cute and small and innocent looking, but he also has an inhuman strength and the sex usually ends with the seme having various bones broken.
The mangaka based the characters on Duo and Heero from Gundam Wing, especially on the way they were portrayed in various doujinshis.
It's one of my favorite manga and so hilarious too! :D
