Okay, I need to explain one of the jokes here, cause it's pretty obscure for anyone that doesn't know Japanese.
Some of you may have wondered why the guy said that the puddings don't work as "side dishes." Without knowing the original Japanese here, he probably used the term お菜, which is often used as a slang term for masturbation material. So, when he said that the puddings don't work as "side dishes" he means that no one could get off to them, but she doesn't know the slang, so she though he meant it literally.
So yeah, there you go. There might be more stuff like this in this manga, but this just so happens to be one that I know about.
