Do opposites attract?

Bruce Patman and Regina Morrow in love? No one at Sweet Valley High can believe it. Regina is beautiful and shy, one of the nicest girls in school. Bruce is a real snob, and the only person he's ever cared about is himself.
Jessica Wakefield figures the romance can't last. She knows Bruce too well. She's even willing to bet Lila Fowler that Bruce and Regina break up within two weeks. The stakes are high, and Jessica can't afford to lose. If she has her way, Regina and Bruce won't be happy for long.

Lila laughed. "If I win, you write my term paper. And if you win, I write yours. how does that sound?"
Jessica swallowed. If she lost the bet, she'd have two term papers to write. And at this point she could barely imagine writing one!
But she wasn't about to let Lila see how worried she was. "You're on," Jessica said cheerfully.
"Fine," said Lila. "We'll make the carnival the cutoff point. Just think, if bruce and Regina break up before then, you won''t have to worry about your term paper!"
And if they don't, jessica though uneasily, I might as well hang myself. She looked across the cafeteria to where Bruce and Regina were sitting and shook her head. This bet is too important to lose, Jessica thought. If Bruce and Regina don't break up on their own in a few days, I'm going to have to do my best to help them!

Will jack destroy Lila and Jessica's friendship? Showdown
