Get the Black Trackmug. ICONIC phrase used by Lee Taeyong, in the Red Velvet's song 'Be Natural', TY comes from TaeYong, at that time, Taeyong was still being part of SMRookies, exactly of SR14B. TY Track means, a Taeyong's track, bcs it was his moment to shine in the song. He didn't performed in live along with Red Velvet. NCT members usually makes fun of him because of his phrase. Remember, ICONIC PHRASE.
