I'm simply going to say this:
On the first episode i was watching i was eating lunch, and after discovering the main premises of the episode being about a guy swallowing another girls spit... I nearly threw up, I am literally being serious, i dropped my food and ran to the toilet gagging.
All i have to say is, what the hell is wrong with Japanese people, not once in the long years of being with my other half have i ever wanted to purposely suck her spit, its ******* rancid.... honestly, I know we need some originality in the romance sector of anime but for the love of god at least let it be something that does not make me want to vomit in the literal meaning of the word.
