NighT started his professional League of Legends career when he joined South Korean team Winners in March of 2015, after some time in a newly created team Winners got sponsored by Ever8 and renamed their team to Ever8 Winners. NighT played for Ever8 Winners in Korean Challenger series but after a somewhat unsuccessful run with the team, NighT was scouted by Giants Gaming as the starting Mid laner for the Summer Split. The team then finished the round robin stage at rank 3 with an 8-3-7 standing. In the playoffs, the team lost to Unicorns of Love (1-3) ending the split at 5th-6th place. With enough points earned from the Summer, they got into the 2016 EU LCS Regional Qualifiers but lost again to Unicorns of Love with the final score being 0:3, which also sadly meant that they did not qualify for the 2016 World Championship. In his first split in the EU LCS, NighT became part of the All-Pro team and bagged the Outstanding Rookie Award. Night signed a new contracted with Giants in hope to achieve something bigger with old and new teammates; Flaxxish, Memento, HeaQ and Hustlin.
