On Dec. 14, Liiv SANDBOX announced that they signed Heo "PawN" Won-seok as mid lane coach. In their announcement, they said "We are pleased to announce the signing of 'PawN' as our new coach. We hope for your support and look forward to us in the future."

PawN started his LoL career in 2013 as mid laner for MiG Blitz. In seven years of his career, PawN played for MiG Blitz, Samsung Galaxy, Edward Gaming, kt Rolster, and KING-ZONE DragonX and won championship trophies in LCK, LPL, MSI, and Worlds. He retired as a pro gamer in 2019.

In the announcement stream, PawN said that he will be working as a specialist coach for Lee "Clozer" Ju-hyeon. Clozer has signed with Liiv SANDBOX for the 2022 season as the starting mid laner for the team. As the veteran meets this young prospect, it'll be curious to see how well PawN will be able to improve Clozer in 2022.
