Lee "Scout" Ye-chan joined SK Telecom T1 during the 2015 preseason as a mid lane substitute; however, the team used only Faker and Easyhoon for the entirety of the 2015 season.
Scout made his debut at the 2015 LoL KeSPA Cup against Ever in a semifinal BO3. After losing game 1, SKT subbed him out for Faker but ended up losing the second game as well and were eliminated. Scout stayed with SKT for the 2016 LCK Season but was removed from the roster after the first half of the round robin In March, Scout left SK Telecom T1 to join EDward Gaming as a mid laner.
During the midseason offseason, PawN stepped down as starting midlaner, and Scout was announced to take his place.
