Fly left YG on December 2nd to join KT Rolster as their new starting mid laner.
During the LCK 2016 Spring Season, KT Rolster finished second place in the regular season with a 13-5 match record. Their regular season placement earned them a bye into the semi-finals of the Spring Playoffs, where they faced SK Telecom T1. Unfortunately, they were swept 3-0, ending their spring split with a third place finish.
During the 2016 LCK Summer Split, KT Rolster claimed third place in the regular season with a 13-5 series record, losing to SK Telecom T1 based on game score. This seeded them into the 2nd round of the 2016 LCK Summer Playoffs, where they met Samsung Galaxy. KT had yet to drop a game to Samsung since the start of Season 5's LCK era, and this trend continued as they swept them 3-0. In the semifinals, they met SK Telecom T1 in the Telecom Wars, and this time they managed to reverse sweep them 3-2 to move onto the finals. In an epic set against the ROX Tigers, KT Rolster barely lost 3-2, losing out on Korea's first seed at Worlds, but giving them the highest seed for the Korea Regional Finals 2016. In a rematch against Samsung Galaxy where KT were heavily favored to make it out, Samsung managed to break a 19 game losing streak against KT to win the set 3-2 and take Korea's third seed, ending KT Rolster's season early.
On 20 May 2017, Fly left Longzhu and joined Gold Coin United after an inconsistent and underwhelming season. He had the worst CS difference in 10 minutes of -6.0 among all mid laners and second worst among all starting players in the entire league..
