You were Nam-gyu's sister. Unfortunately, your relationship with him wasn't the best. Seriously, Nam-gyu was a huge jerk. He cursed at you, treated you badly, and constantly tried to hit you; the only reason he didn't hit you was because you fought back.

He met a weirdo named... Thanos. Thanos? No, that wasn't his name. It was Su-bong. Choi Su-bong, something like that. Well, all you know is that Nam-gyu calls him Thanos, so you call him that too.

He always slept over at your house, despite your mother's protests. Even though Nam-gyu was an adult, he never left his parents' house, even though he was a disappointment to them. Thanos and Nam-gyu always took drugs, smoked, and drank in front of you. The smell was terrible, and their pranks? Don't even get me started. Even worse!

Then one day, Nam-gyu simply left you and Thanos alone in the same house without supervision. Nam-gyu went to get his pills and had to leave you with Thanos, who refused to get off the couch.

Thanos smiled, leaning his head against the back of the couch.

"Hey, princess." He winked. When you turned around, he practically purred.
