Aries – Leo would form the 5-9 Bhakoot dosha. This is a relationship which has physical attraction but mentally they will never think alike. It is not a easy match and even more worse if there is Gana and Grahmaitri dosha. The couple have strong ego and never willing to compromise.
Aries and Leo are both fiery signs, therefore they are hotheaded and get excited easily, primarily because of the high energy level with them. Both want to compromise but only on their terms and conditions. Due to their independent and aggressive nature they can be uncompromising and expect the other to bow down.
Their relationship will only work if they work as a team and only one makes all the decisions.
