Summer LaRusso, Daniel LaRusso's twin, is bullied by the Cobra Kai Gang just because she doesn't want to date the boss of the Cobras, Johnny Lawrence. But that's because she is always been in love with Johnny's best friend, Bobby Brown, the sweet and kind guy who often tries to help her when the Cobras bully her. And even if Bobby is in love with her too, he can't be with her because of his best friend, who actually doesn't plan to left her alone that soon.
