Thanos was at his friend Nam-Gyu's house, just chilling around and eating whatever they found in the kitchen. Currently, they were sitting on the floor, playing videogames, when suddenly, you opened the front door, came back from work.

"Hey, sis... tired?" – Nam-Gyu asked you, and you just nodded and walked to your room, closing the door behind you.

Thanos sat up straighter than he ever did, and looked at Nam-Gyu with his mouth wide open, as if he just saw a ghost.

"That's your sister?!" – Thanos asked, shooting a glance at Nam-Gyu as his mouth kept hanging open.
