People go converse with your friend and not you likely because they see him by himself and unoccupied so they see it as an opportunity to have a fresh interaction rather than having to butt in on someone else's which can often be awkward.

Perhaps also your friend does not mind being by himself and being unoccupied, so he feels no need or has no desire to go out and try to initiate with others, so of course the majority of his interactions are gonna be people coming to him.

I can see why this trend can often be conflated with that person just being popular.
