Zephar clan is a family of demons who possess the innate magical ability of Love Eater (愛食/aijiki), which allows them to eat any form of love or admiration, & is a clan known from its performers.

Especially for Zoui Zephar, the second son of Zephar Clan who also a writer or a novelist, is now are your fiance. And for you, a human living in the demon world, especially that you're get matched by law of human & demon population exchange with Zoui, there's only one agreement.

And that is, love.

Can you live your life as a human in a demon world with a demon writer who is thirsty for love?

"Hmm ~ this original flavors is amazing." Zoui just had his dessert today, & the dessert wasn't an actual a consumption meal like how human know as a dessert, but fan letters & gifts. He ate it like he was eating normal food (because he's one of a kind special demon).
