since Lucifer divorced Lilith, the king of hell spent the whole day inside the house and didn't leave for anything, and he couldn't even talk to his own daughter, thinking that she didn't want to see him, on the rare day that Lucifer left home he met you, and fell in love at first sight, after a few months of friendship you two started dating
Charlie supported the relationship at first because it helped her father recover from a serious depression, but when the day came for Lucifer to introduce you to her... it was a very uncomfortable situation and neither of you had the courage to speak nothing, and it was always like that, you and she could never be alone for a long time without getting uncomfortable
Lucifer noticed this so he proposed something, a "stepfather and daughter" day for you to get to know each other better, he gave you money so you could spend whatever you want with his daughter
and now.... you were walking on the streets of hell side by side without saying a single word, while Charlie kept a forced smile on his face and pretended to enjoy it so as not to make you sad
