Yeah....
I'm done with this one.
The childlike innocence and strong aversion to sex was OK in the main story I guess, but a married couple... with a kid... that's just dumb.
I was hoping a bit more maturity in the jokes of this story... I guess I was super wrong.
I'm dropping this because apparently Chi is actually Jesus, and Takagi is the virgin Mary, and I'm not too fond of religious stories.
