On November 14, T1 announced that they agreed to part ways with bot laner Park "Teddy" Jin-seong through a mutual agreement. In their tweet, they said "Today we part ways with ‘Teddy’ through a mutual agreement. We truly appreciate his contributions including 3 LCK Championships and being part of the Semifinals at Worlds. We wish him all the best in the future."

Teddy started playing in LCK from 2017 as a bot laner in Jin Air Green Wings. After two years, Teddy joined T1 in 2019, winning 3 LCK Championships and qualifying to Worlds 2021 for a semifinal finish. Although Teddy's contract was signed until the end of 2022, T1 mutually agreed to end contract for Teddy to find a new team.
