They both have a sense of justice and a desire to see the realm in a better state. This could lead to them forming an alliance and working together to face the various threats in Westeros.

For example, Jon wants to protect the North and all of Westeros from the threats beyond the Wall, while Rhaenys may want to reclaim the Iron Throne for the Targaryens. As they work towards these goals together, they could start to respect and love each other.
