The Front Man in season 2

The Front Man absolutely stole the whole show. The acting was brilliant, the way he misleads other characters, pretends to be their ally etc.,the development of his relationship with Gi Hun was portrayed so well. Why do you think he decided to participate in the games again tho? I personally think he wanted to teach Gi Hun a lesson, show him it's impossible to destroy the system and even if they try to convince people to leave the game it's still eventually their own decision to participate. Maybe he just wanted to destroy Gi Hun's whole belief system about the world. He's still so mysterious though.
