Koi wa Hitochigai Kara

Overview

Belinda Kelly didn't have the most fun in high school. A little overweight and a lot bookish, Belinda was more interested in getting ready for law school than hitting the gym. Still, one boy saw through her glasses and peered into the sweet soul of the girl behind them. He always tried to help her out. Taking her to a dance turned disastrous, though, when his friends played a horrible prank on her. Ten years later, now going by Rachel, Belinda has transformed herself into a star lawyer who can turn anyone's head. Her goal: destroy her high school date and the two friends who pranked her by teasing them with what they could have had but never will. Problem is, time changes people, and she may have picked the wrong target: the first man she chooses is the kind brother of her former tormentor! (Source: Renta!)
