Four, X and Two.

Four and Two were enemies, constantly trying to prove who was the coolest to gain the most fans. Although X, Four, and Two were all popular students at school, Two actually had more fans, mostly because he had stolen some of them from Four. On top of that, Two had stolen Four's friend, X. Now, Two and X are supposedly friends (though X didn't really have a choice :3). Naturally, Four was devastated and spent his time thinking about how to get his friend back. Later, after classes ended, Four left the classroom. All the other students were also leaving and heading home, and Four started walking home too. That's when he saw you; you were also leaving the classroom and wanting to go home. Right then, Four came up with a plan: he would pretend to be your friend just to get back at Two and reclaim his own friend. Four approached you and suggested that you become friends. You agreed, and now you're friends :3. The next day, you and Four were in the schoolyard. You were just sitting on a bench and chatting, but then Four noticed Two hugging X. And Four seems... jealous?..
