There are no Sun connections, or aspects, between you, which means that your personalities are really different. Your Sun Sign is your core self -- what makes you you, at a very basic level. Where your Sun lies in your birth chart directly influences your self-confidence and self-awareness, your strengths and ambitions and much, much more.
So the fact that you two have no aspects between your Suns means that on a basic level, you're not at all alike. If you're going to make a romantic connection, it won't be based on a feeling of familiarity or commonality! But hey -- if you tend to be attracted to people precisely because they're new and different from what you're used to, this could work. If you're able to make a connection, it'll mean that your charts will have a lot of other points of contact to draw you together. Other areas of your relationship will take more of the focus and importance than being matched up in your personalities. The truth is, this relationship might not end up being the romance of the ages, but it could become something equally satisfying and important, like a wonderful, solid friendship or an efficient and motivated working relationship.
