Lucius pov
I was following allister thinking of like 1 million things at the time like how am I going to propose to(y/n)or how am I going to kill allister when we got to the piano I notice that if I pull one of the wooden polls it would fall brutally on allister
So I went with that
-10 minutes later
I finally kill allister before anyone noticed I ran upstairs to get ready before 1:00pm
Your pov
I was waiting for Lucius on the garden balcony it was almost sunset when I turn around I notice Lucius he look nervous then we talk for a bit and then Lucius said
Lucius:(y/n) I have something to ask you
You:yes Lucius
Lucius:you see we have been gf and bf for 6 years and I wanted to ask you... WOULD YOU MARRY ME?!
You:oh Lucius of course I would marry you
Then out of nowhere jumped Lucius father
Lucifer: YES THATS MY BOY WOHOOO
you and Lucius:uhhh?
Lucifer:oh sorry I would go now you shall continue (ninja vanishes) pufff
Lucius:shall I
You:you may
(N):you and Lucius kiss for a bit and Lucius carries you bridal style and go to bed you ,Lucius and his father discuss about the wedding to be celebrated in 2 months
So that would give them time to prepare and for Lucius finish with his work
