From Renta:

The Onigami shrine, where demons are courteously worshipped, is found in a small village in the countryside of Japan. As always, a young demon gazes warmly at Higure, the son and heir to the shrine. "Ahhh!! He's so hot... I can't handle it... he's priceless..."
This young demon named Kouen has fallen for Higure, who once saved him and was so kind to him when he lost his way and wandered into the human world. On the day that Higure turned 18, thunder and lightning struck and Kouen descended in front of Higure. While he intended to act cool and tell Higure how he intended to take him as his wife, his plans end up turned upside down.
"You don't know...? This is how humans confirm their love for each other."

A true love story between a black-hearted high school boy and a foolish demon with beastly eyes... The story of two love birds, so hot you wouldn't want to interfere with, has just begun!!
