It started serialization on Flex Comix's web manga FlexComix Blood on August 10, 2007.

[7] Junpei Kōsaka is a second-year high school student who is allergic to cats, and because of this he hates the sight of them.

As luck would have it, his high school crush, Kaede Mizuno, absolutely adores cats.

One day, while walking home from school, Junpei kicks an empty can and unfortunately breaks the local neko-jizō-sama (guardian deity of cats).

He calls the humor "cute", and that the ending builds up to something nice despite the manga not being finished.
