Lee started his season with a new free program, "Queen medley", but returned to his previous season's free program, "The Barber of Seville", at his first Junior Grand Prix event. He won South Korean Nationals, but could not compete at the senior World Championships because he did not meet the minimum technical score requirement for the event. He placed 13th at the World Junior Championships. In February, he landed a triple Axel jump during the short program segment at the Four Continents Championships.
