The Aryans were the invaders from the north who are believed to have conquered the Dravidians in the Indian subcontinent around 1500 BC. This period marked the beginning of the Vedic period in India.

the aryans, but the dravidians were living in India first. The aryans settled in the north and pushed the dravidians into the deccan plateau.
Some South Indians are attracted to North Indians and it is the same with North Indians. I am a Syrian Malabar Nasrani and our ancestors were converted from the Brahmins who migrated from North India. If you ask me they were the purest of the Brahmins. As they did not even let other Brahmins come near them as they believed they would get polluted. By the way your question is written it sounds as if you think South Indians are Dravidians who were conquered by Aryans. You must understand the Dravidians aren't the tribal people who are really dark-skinned and have flat noses also bushy hair. Also not all South Indians are Dravidians. I would say about 21% or more South Indians have Aryan blood running through their veins. The rest of South Indians are either from the lower castes like the Pulay who look very similar to Adivasis and the Drsavidians such as the Ezhavas in Kerala.
