Friend’s list question – Social Network Analyzer Review

So, I used to click and check my friend’s profile (person B) all the time that’s why I think he became my number one. these past few days, I stopped checking his profile and messenger (person B). I started to chat with my other friends and check their profiles. Sometimes, these other friends would be my number 1 but after a few hours person B comes back to number 1. Person B never likes, comments, nor chat with me on Facebook, so, I was wondering what would be the reason why person B keeps coming back to top 1 despite my interactions with my other friends?
