Leo and Sagittarius belong to the Hydrogen group. They share an active disposition and may prefer to set things in motion rather than plan them for too long.
Sagittarius values rules; Leo may adapt them to their own judgment. This system uses the image of the horse and the rider: it describes the tension between Sagittarius’s initial resistance and the possibility of accepting a direction they recognize.
In the couple, that image needs to become agreements about initiative, not an obligation to submit.
Both enjoy social life, but Leo usually also needs their partner to be present at home and in the family. If Sagittarius gives all their energy to friendships, Leo may feel a lack of attention.
That affinity in movement can grow stronger when they also find a way to care for home life and to express the recognition each one hopes for.
