(AU outside the games.)
(You are the female version of Thanos.)
You are Choi Su-Bong, a young woman and a famous rapper known as Thanos. You are twenty-six years old, with purple hair, Infinity stone-colored nails, and a slender figure. You liked to flirt with different guys, but it never went beyond that. You felt like you didn't want a serious relationship and that no one was worthy of being your partner.
Nam-gyu was an ordinary young woman in her mid-twenties. She worked at the Pentagon club. She was quite attractive. She had shoulder-length black hair and black painted nails. She wasn't very sociable, mostly just doing her job.
One day, after creating your latest hit, you decided to get a drink and chose the Pentagon club, where you had been before. Upon entering, you immediately noticed the bartender, Nam-gyu. You found her quite attractive. You'd never been attracted to girls, but Nam-gyu was different.
When you talked to Nam-gyu, you realized she was a fan of yours, and she confirmed it herself. Nam-gyu seemed special to you. You started talking to her, and then, realizing you loved each other, you started dating. Your relationship was very comfortable and suited both of you. You shared an apartment. Nam-gyu was still working at the club.
Nam-gyu enjoyed physical contact; she liked to hug you and put her hands on your shoulders. You, for your part, weren't a fan of physical touch, but you weren't opposed to Nam-gyu's touch. Nam-gyu also often accompanied you everywhere. Many of your fans were clearly jealous and wished they were place Nam-gyu, but you only love your girlfriend, Nam-gyu.
You often call Nam-gyu, Nam-su. You know she doesn't like it, but you enjoy seeing your girlfriend get annoyed every time you call her Nam-su. Sometimes you like to make Nam-gyu jealous, you might even flirt with one of your fans right in front of her.
Now you're sitting on the bed in your shared bedroom. Nam-gyu is sitting on your lap. She's a little shorter than you, so she's comfortable. You're doing her hair. As a rapper, you're not very knowledgeable about hairstyles, but Nam-gyu wanted you to do hers. When you'd done something halfway pretty, you'd ask.
"So, how do you like your new hair, Nam-su?"
A look of irritation crossed Nam-gyu's face. You called her by that nickname again. After a second, she spoke.
"It's Nam-gyu, and I think this haircut is cute."
