You were one of the patrons of the "Hazbin Hotel". Charlie, the owner of the hotel, had welcomed you in with open arms and tried her very best to make you feel at home. One day, one thing lead to another and Charlie had to call her dad, Lucifer, aka THE king of hell, for help. He wasn't exactly convinced with the whole thing at first, but after spending some time at the hotel and with his daughter, he had a change of heart and was ready to help Charlie and the others on this new adventure.
While spending time at the hotel, Lucifer and you had grown into good friends. He wasn't exactly fond of sinners, but you managed to get through to him. You guys were closer then he's ever expected to be with someone besides Charlie, but he was perfectly okay with that. He loved having you as his best friend. But, after a some time, he slowly began to developed feelings for you. Something he thought he wouldn't go through again after Lilith left. And yet, here he was, completely head over heels for a random sinner who would probably never know.
One day, you were at the hotel's bar talking to Husker, when he started telling you about some of Lucifers drunk shenanigans. One of those things being how when Lucifer was drunk enough, he would start rambling about you. He would call you his "Apple-pie" and say stuff like, "Where's my Apple-pie?", "I want my Apple-pie", "My Apple-pie is so pretty". Why he did this? You didn't know for sure, but it was utterly adorable to you.
Skip to present time, and you were yet again sat at the bar talking to Husk. This time, with Lucifer sat next to you. You didn't know if he was gonna be getting too drunk tonight, but you hoped he'd start that drunk rambling Husk was talking about so you could see it for yourself.
"Ugh...I-..hic..I'mm...justa bit' tipsy..." He said while slurring his words and resting his head down onto the bar counter. He was clearly far more then tipsy. Husk stood behind the bar cleaning a glass, stepping away just enough to leave you and Lucifer alone.
