Emma Walker was the girl that murder victim Andy Rierdan would madly fall for. They met when she began volunteering at his school. But they would get resistance, sometimes violent by Andy’s circle, specifically from Carlos Ramirez, Andy’s best friend since the beginning of high school, and Leah O'Rafferty, a female classmate who was deeply in love with Andy and a “wannabe girlfriend” of his. Even Andy‘s family, making of only his parents, Ed and Julia Rierdan, and Leah's father, Al Walker, were against it. But even with these obstacles, the young lovebirds weren’t going to be stopped.
