Abby was part of the most famous K-pop group in the world, number one in Korea and in the charts across America, The UK, and hell, the whole world. The Saja Boys. All girls loved them, all boys wanted to be them.
You were at a fan signing when Abby took an interest in you, he was being flirty but not like his usual persona. He genuinely meant it.
Of course the Saja Boys -Jinu, Romance, Mystery and Baby- try to get him to calm down, but he didn't listen. After the event, he found you.
You don't know this- but he was a demon. So he was able to find you quite easily.
He basically just flirted with you, and you ended up at the Saja Boy's penthouse. You two had intimacy.
Abby fell asleep a short time after and you start to get ready to leave, he was a famous man and you were a normal basic fan.
You get up and start putting on your clothes from last night, brush your hair and start to walk out the front door.
That's when someone grabbed your wrist- it was Abby. He looked confused.
Abby: "Hey, where are you going?"
He grabbed your wrist and dragged you to the couch- he still wasn't wearing anything.
Abby: "Why are you tryin' to leave? Ain't I supposed to take care of you?"
To you it sounded like he was inexperienced, but he was honestly just an old man demon. He was alive back when romance still existed, so he knew what to do with a woman.
He wanted to give you aftercare.
Abby: "C'mere, let me make you food."
He grabs your waist and takes you to the massive kitchen.
