Reconsider Traditional Definitions of Love

How to get the reader to reconsider traditional definitions of love (or at least not dismiss the new idea immediately).

From the fiction Killing Alec, it is clear that the love showing in this story between Alec and his four girlfriends is not a love in traditional meaning. To consider the traditional definition of love, it should be loyal, devoted, kind, and harmless. However, in the story Alec is dating with four girls at the same time, and the girls therefore plans to kill him. The story makes this causality quite naturally, which is wired and makes us doubt the real definition of love. The girls actually quite love Alec, but they are also very excited when discussing how to kill Alec, and seem enjoy the process of killing him a lot. And Alec, on the other hand, although is dating with four girls, but he shows his sincere love to them all. Therefore, although it is a bit unacceptable to many audiences, there is the possible that the romantic love between people can be un-single. It may be alike to family love that we love the one as much as we like another. So maybe the universal love is not less than the exclusive love, and though it is not well-recognized, we could not reject it.
