A plot twist might be that their kiss is actually a way to transfer some sort of energy or knowledge. For instance, Gwen has a special ability that can only be passed on through a kiss, and she gives it to Kevin without realizing it at first. Then, Kevin starts to experience strange things because of this new ability. Or, the kiss could be a test. There could be a higher power or an old wizard testing their love and commitment, and if they pass the test, they are rewarded with something really special like the ability to save their world from a great danger, but if they fail, they lose each other forever.

Maybe the ex - partner spreads false rumors about one of them, which causes a rift between Gwen and Kevin.
Well, perhaps Kevin kidnaps Gwen because he wants to use her as a bargaining chip against Ben.
