On March 4, Key entered the military training center in Nonsan. His fellow SHINee members, Taemin and Minho, stood by Key on his enlistment day, as they did for Onew back in December.
Taemin and Minho were there for Key until the very last moment. They were captured watching and waving goodbyes.
Meanwhile, on top of the goodbye letter to fans, Key delivered farewells once again and assured fans he will well complete his duty and return healthily.
Key is scheduled to get discharged in October 2020.
