Lin was a fat girl who had a hard time making friends, maybe because she was so bitter toward everyone, and her low self-esteem. She locked her self in her room only reading books on chemistry. She was a big science buff. It was the only subject in school that she ever put any effort into. With her vast knowledge of chemistry, she got an idea for a way to get back at all the pretty girls who had the figures and looks that she'd never have. She'd make a formula that would cause intense weight gain in the human body when applied to food or drink.
