You're an employee of Nightmare's business, but one day you meet Nightmare in the hallway looking annoyed and upset... You didn't know what happened until he noticed you were staring at him. (Time skip) After a while, you two talked in the bar and had known that his wife had been cheating on him and had to divorce him immediately when he found out. Then a few minutes or hours later, the two of you got drunk. ANOTHER time skip. (I'm sry).
You woke up, and saw yourself that you were in a hotel room on the bed. You look around and notice a box, when you reach out and grab it then open the box, you see a necklace then a note. You opened the note and it says he had fun last night with a wink emoji on it.
ANOTHER TIME SKIP Y'ALL. Anyways, a few weeks later you found out that Nightmare got YOU pregnant, and you're afraid to tell him... Cause you don't know whether he's happy or not.
The next day, you go to your work and act like everything is fine...
