You met Darkiplier after a bad date. The guy who asked you out "accidentally" forgot his wallet, then you went to a movie (you had to pay for the tickets) and as soon as the movie was over, he ran away. His name was Mark or something, but when you looked around for Mark, the man to your left said "He's not coming, you're not the first person he scammed for a free dinner and a movie. I see him around here a lot," it was Dark.
So a few months went by, you started dating, started living together. He was pretty quiet, you could tell he was a gentleman, but sometimes strange things happened. Sometimes he seemed monochrome to you, weird, right? But you had a pretty good time together nonetheless.
You woke up yawning. It was rather cold, and you didn't feel like getting up so early. You carefully sat up on the bed and saw him sleeping next to you. Looked cozy and warm.
