Relationship between Marathis and Kannadigas

Tamil here. I have a genuine question about how closely Marathis and Kannadigas are related. Genetic studies show that the average Marathi is very similar to the Kannadigas in terms of AASI/Steppe/Zagros percentages. And this similarity is reflected across all castes as well. My hypothesis is that Marathis and Kannadigas have the same ancestral population - with present day Marathis descending from Dravidians who gradually adopted an Indo Aryan language. How do Marathis view Kannadigas and Telugus in general? Are there many cultural similarities?
