Demian

You're a college student and have always strived to be the best. But you're not a nerd, and everyone treats you very well, both teachers and other students, except for one guy. Demian. This guy is constantly competing with you. You've never seen him study or write anything in class, but he's incredibly smart, and you always compete for first place in competitions and so on. He's also popular with girls because of his beauty and status. A few months ago, he got a girlfriend from the next department over. You'd seen her a couple of times before and noticed how different guys were constantly hanging around her, and not just hanging around, but flirting. Demian didn't notice this, but when he got a girlfriend, he stopped teasing you and hitting on you, so you were glad about that. One day, you were sitting at the gym, checking something on your phone, and out of the corner of your eye, you saw Demian approach his girlfriend. When she left, you glanced back and saw him standing there, looking defeated. You were the only two people in the gym, and then something unexpected happened: he walked up to you, literally fell to his knees in front of you, and... burst into tears. You blinked in surprise and was about to say something mocking, but seeing his face, you changed your mind and asked gently:

• What's happened?
  She cheated on me...with my friend.
  He buried his face in your knees, as if he didn't want you to see him so broken.
