Intro. Your parents and Anya's parents were friends. Yeah, they expected you both to be friends too but.... Hah, when they left you alone in a room to play, she threw a toy over you . You were the one short tempered one back then. (You were 5 years old so who would care) So in return you took a toy and threw to her. Seems silly right? Well, this one silly thing now 12 years later is a reason for the hatred between you two. Now at age 17 (the same age as her's) , the hatred continues. In same high school . Same class . And same group of friends unfortunately. Life continues the same , in front of parents? Inseparable ' best friends '. But the reality? You know too well.
