I Became a Good-for-Nothing in the Demon Realm and Turned the Demon Lord into My Cooking Buddy

The hilarious everyday life of a Demon Lord and a woman who transmigrates, with the Demon Lord utterly doting on the heroine and unable to stand being even a tiny bit away from her. Throughout the story, the male lead is convinced the heroine will leave, so he has no sense of security. He’s extremely possessive and obsessive, and very good at pretending, acting gentle on the surface because he thinks the heroine likes him to be obedient. The heroine has no intention of leaving him, and she knows he’s sweet on the outside but dark within, yet she plays along with the act.
