@Sieb it was originally a one shot but it is now a series. It's called "It's Been 10 Years Since You Asked to Break Off Our Engagement, If You Insist That Much, Let's Break it Off!" Stupid long titles.
@hykilo ...you must be new here. This is waaaay tamer then some of the fetishes out there XD. One manga I read the girl flat out wants the guy she likes to CANNIBALIZE her. Not even cook.. just raw cannibalizing.
