Solomon whispered in Diavolo’s ear, “I have something from the human world that might interest you.” Diavolo raised his eyebrows with interest. “Oh?” From his robes Solomon pulled out a leafy bouquet with white berries on it and tied together with a red ribbon. Diavolo took the bundle curiously. “What is it?” “Mistletoe,” Solomon explained, “It's a magical plant from the human world. When two people stand under it they are compelled to share their feelings for one another.” Diavolo started to hold the plant above them, wanting to see if it worked or not, but Solomon quickly pushed his hand down. “No, no, no. You can’t just use it on anyone… I just got a splendid idea! How about you try it on Lucifer. I’m sure he would appreciate getting to experience something unique from the human world.”
Solomon gave a closed eyed smile that made Diavolo feel he hadn't just come up with that idea on the spot. However… he had to admit he was interested to try it out on Lucifer and find out how his close companion really felt about him. Ah! He was already getting his hopes up that his feelings for Lucifer were mutual. “Thank you Solomon.” “Of course, how could I pass up an opportunity to help the future king of the Devildom? Don’t tell Lucifer you got this from me though. It will be more special if he sees it as a gift from you.” Again that smile, but Diavolo’s thoughts were already focused on making plans on how to surprise Lucifer with the Mistletoe.
Diavolo decided on hanging it above Lucifer’s office door as that is the easiest way to catch him. Just as he finished tying it, the door creaked open. “Diavolo?” “Ah! Lucifer!” Diavolo quickly dropped his hands, trying not to look at the foliage. Lucifer held out a hand and Diavolo stared at it confused. “Come on hand it over I don’t have all day,” Lucifer said. “What?” “You came here to drop off more paperwork right?” “Oh, no… I came to take you out to lunch! Yes that's why I’m here!” Lucifer squinted at him suspiciously, “Diavolo, it's 10am.” “Brunch then!” He grabbed Lucifer’s hand and Lucifer stepped forward right where he wanted him to.
There is an explosion of sparkles and the sound of ringing bells and suddenly Lucifer is leaning forward to land a kiss on Diavolo’s lips. “...” “...” Lucifer flustered, jumped back. “D-Diavolo, I’m sorry. I don't know what came over me.” Diavolo stared at Lucifer’s flustered complexion with stars in his eyes. Based on the expression currently on the demon’s face, Lucifer definitely felt the same way about him as he did about Lucifer. It worked! It actually worked! The kiss was a bit of a bold way for Lucifer to show his feelings though, not that he minded. He would have to do something for Solomon to show his gratitude.
“I s-should get back to work,” Lucifer stuttered. The demon was looking very much like he wanted to escape behind his office door. Diavolo wasn't going to let that happen. He leaned down, landing another kiss on Lucifer’s shocked face. “Me too,” he whispered. “W-what?” Lucifer sputtered. “I like you too, Lucifer.”
