On November 8, T1 announced that they part ways with interim head coach Son "Stardust" Seok-hee. In their tweet, they said, "At the request of 'Stardust', we part ways as he looks for a new opportunity. We truly appreciate his contributions to the team and wish him all the best in the future."

Stardust joined T1 as an assistant coach for this season but changed his position to interim head coach this July after T1 terminated Daeny and Zefa's contracts. After this change, T1 finished as the runner-up in the LCK Summer split and advanced to Worlds for a top 4 finish, losing to DWG KIA in the semifinals.
