Can Cancer and Aquarius start with brother and sister? Cancer Aquarius, is this good?

Cancer pursues stability, Aquarius pursues freedom. Aquarius is euphemistic and affectionate The air signal is unstable. In theory, there is not much overlap, but if you start with brother and sister, you can have a long running-in period to find out what the other person and yourself really want. It might be good for both of us. If you really like it, it's a good idea. I may not wish you happiness.
