Same sign
Partners of the same sign mirror each other: the same values, reactions and pace. That gives instant understanding, but also amplifies shared weaknesses - nobody balances out the extremes.
Elements
Two water signs understand each other almost without words. You are both sensitive, emotional and long for deep closeness. There is a lot of tenderness in this couple, but also a risk of drowning in shared worries and hurt - someone needs to keep a clear head.
Pace and temperament
Both signs are cardinal - initiators used to starting things and leading. Together you launch shared projects easily, but you need to divide roles, or each of you will pull in a different direction.
Cancer in love
In love, Cancer needs to feel safe. It opens up gradually and looks after its partner like family. Cancer hopes for the same tenderness, attention to small things and certainty that it will not be abandoned. Harshness and indifference hurt it more than it shows.
Why one sign isn't enough
Sign compatibility compares only the position of the Sun. Even two couples with the same signs have their Moon, Venus and Mars in different places - which is why it comes easily to some and takes work for others. Exact compatibility is calculated from both partners' birth charts.
