Sara Lin is an 18-year-old high school senior & she loves making bets with her best friend Patrick. After Sara's 18th birthday, two new students came to her school, Joe and Oliver Yang, who were brothers. Sara had met Oliver before at the subway, where Patrick bet her that she wouldn’t go up to a random stranger, Oliver, and ask him to kiss her. But she did ask him, and in turn he said no and called her a weirdo. Joe doesn’t know anything about it.
