Kinda still on the topic of Lucifer being a softie especially around Christmas-
Lucifer’s the type to keep a branch of mistletoe in his pocket just so he can hold it above your head and kiss you under it <3
Lucifer loves tasteful christmas lights- is what he says, really he loves them all!!!! and it’s honestly so cute to watch how his face softens just a little bit when he looks at the Christmas tree in the HoL. 
He would absolutely love to take you on a late night drive, down the snowy roads ‘hunting’ for house’s coved in christmas lights~
He has special wrapping paper for each of his brothers and you ofc!! (Mammon’s is very flashy gold paper, Levi’s is the classic orange and white strips, Satan’s is that cat meme wrapping paper!!! Asmo’s is plan baby pink~ Beel’s is that goofy fast food print ‘n Belphie’s is that extra pretty gift paper that’s covered in constellations!!)
Stockings are his favorite part of Christmas morning!!! Because, while Lucifer knows exactly what he put in everyone else’s stocking his is always filled with a very odd assortment of little gifts from his brothers. But nobody ever really acknowledges it- it’s just another one of their quiet traditions. 
Extra note; I’ll probably add more to this later!!! but if I don’t post it now I’ll forget about it 🏃🏼♀️💨
