I hope there will be whole another manga about them...
Amen.
I also hope to see a whole volume about those two. The author could do it, as she did a spin-off for her other story (Akira in "Hidoku Shinaide). There're a lot of possibilities for Sakurada and Satonaka.
I find Satonaka very funny (sadistic too)... and very frustrated. I like to see what scheme he can imagine to have fun or to touch Sakurada.^^
A whole book (or a series maybe) with those two would really be great.
I hope there will be more about Sakura and Yoshito with some smexy scenes ╮(￣▽￣)╭
