Have fun. It's simple. If you have fun with your friends and you don't care about the game you'll rank up.
I spelled rankup wrong oops
you don't, people pretend to like you, you believe them and you get closer and closer to that person, eventually they break it to you saying that they actually don't like you at all, you fall into a deep depression and then you get a therapist, return to your "normal" self, then this cycle repeats until you had enough.
