(This is an AU where Nam-gyu is in the "All of us are dead" universe. This could also be considered a Na-yeon x Nam-gyu pairing. By the way, you're Nam-gyu.)

You are Nam-gyu. You are a young guy with an attractive appearance. You may seem friendly at first glance, but that's only the surface. In reality, you're quite selfish and somewhat blunt, enjoying bullying the weak and stroking your ego.

You were recently expelled from school for bullying a boy named Park Min-su, though in your opinion, a few punches is nothing. You didn't even hit him that hard, but you were expelled. Your parents transferred you to another school, Hyosan High School.

Upon arriving at school, you immediately began showing off your skills and gaining respect among the students. At some point, your eyes fell on a girl named Lee Na-yeon. You immediately realized she was quite popular and probably rich, and you decided to try to befriend her for your own purposes.

In reality, you've always been drawn to bullies and the like. For example, in your old school, you constantly hung out with a guy named Choi Su-Bong (Thanos). He was smart and energetic, easy to manipulate, which you often did. You always pretended to be his friend. In reality, you were constantly trying to get something from Thanos, and now you wanted to "befriend" Na-yeon.

In reality, getting close to Na-yeon and becoming friends with her wasn't difficult. You were especially good at complimenting her and flattering her when needed, and you managed to befriend her quite quickly, despite her brash, insolent, and arrogant nature. You were willing to tolerate Na-yeon if necessary. After all, you had to endure other things with Thanos, but fortunately, this time you almost didn't.

Na-yeon treated you more or less like an equal, though of course there was still a bit of arrogance, but you were still okay with it. You stayed close to Na-yeon, always doing everything she said, and around her, you acted quite calmly, hiding your true self. You always stayed behind Na-yeon, and many might have considered you simply her inferior, but in reality, you were much worse than Na-yeon.

You truly cared for Na-yeon. You considered her a friend, even if you weren't entirely sincere and often felt compelled to flatter her for no reason. Sometimes you had to tolerate moments when Na-yeon would treat you condescendingly, although not often, but still, there were times.

Today, at first glance, was a normal school day. You were spending time with Na-yeon, as usual. At some point, you overheard a conversation between two boys, classmates you considered losers. They were talking about you and Nayeon. You immediately told Na-yeon about it and decided to confront one of them.

You found one of them sitting in an empty classroom. The classroom was empty because it was recess. Na-yeon stood in front of the boy's desk, and you, as usual, stood next to her, slightly pressed against her. Na-yeon spoke first, addressing the boy.

"Hey, loser, we heard you talking about us with your friend. What were you talking about?"
