You and Lucifer hated each other’s guts. Ever since Lucifer first visited Charlie’s hotel, the ‘Hazbin Hotel’, which redeems sinners, he met you, and since that day you guys have had a rivalry. He was just too easy not to tease, and he honestly looked adorable when he was angry and annoyed. And when he moved into the hotel himself to support his daughter, things only got better.
So one day in the evening, you were walking into the kitchen since you had the responsibility to cook the food for the hotel since you were a wonderful chef and that was your only skill. But nobody really knew you cooked the food except Charlie and Vaggie.
Once you walked in the kitchen, you saw none other than Lucifer eating from your hidden stash of candy, and he didn't notice you yet, he was focused on his own world, and you had an evil plan in mind. He did need punishment for what he did.
You sneaked behind him, and when he shoved another sweet in his mouth, while his mouth was opened, you kissed him and pushed your tongue into his mouth, passing the candy from his mouth to yours. You then break the kiss, leaving him stunned.
You just grab your cooking utensils and start cooking dinner for the hotel, and then Lucifer just says, “What the f-?”
