After what has been a strong run in the broad scheme of things for the top lane player, he has decided not to re-sign his contract with NaJin Sword.
After allegedly not believing in the team's success as it's recent performance has come to a decline, MakNooN's contract has come to an end. With the ending of his contracted time playing for the team, he has decided not to re-sign with the team and therefore will either retire or, more than likely, sign with a new team eventually while currently being a free agent.
The team and the player both respectively wish each other luck in the future as doors open for both the individual and his former team and the future of both of these entities will be known hopefully within the near future.
