One key element is their meeting. How they first encountered each other was the start of their love journey. Another is the mutual attraction, which was likely based on different qualities they saw in each other. Also, the role of Kaurwaki in Ashoka's life as a support system during his rule is important.
Well, first of all, the cultural and historical context of the Mauryan empire is a key element. In that environment, Ashoka and Kaurwaki's love blossomed. Their personal qualities played a role too. Ashoka's leadership and Kaurwaki's unique charm were factors that attracted them to each other. And the way their love influenced the political and social aspects of the empire is also very significant. For example, Ashoka's more compassionate rule could have been influenced by Kaurwaki's presence in his life.
