On January 12, 2025, NCT 127 took over the stage with their performance in the SMTown Live 2025 event hosted in Gocheok Sky Dome, Seoul, South Korea. The grand event marked the 30th anniversary of the Korean entertainment company, SM Entertainment. While NCT 127 was performing their track Fact Check on stage, the team member Johnny seemingly faced some mic disturbances.
Johnny, aka Suh Young-ho, initially was trying to alert from the stage that the microphone was having troubles, but when he saw it wasn't getting fixed, he hurriedly left. The idol walked backstage to fix his microphone before returning to his spot on stage after a few moments.
Even after returning, Johnny did not lip sync with the song and instead chose not to sing his part. This was soon noticed by his fans, who came out in his support.
Johnny’s admirers flooded the internet with their reactions to the whole mic disturbance scenario. One user on X stated:
“Johnny a real one for that, don’t ever make Mr Suh mad”
Many other mixed reactions for NCT 127’s Johnny were seen online. Some argued that the team should not have made him "mad," while others blamed his management for not allowing him to sing at all.
“istg johnny is the type who always wants to sing in every performance bc we can hear clearly his voice.. and ofc it upsets him if the mic is the problem :/ damn they wont let him sing at all huh,” a fan wrote.
“it broke my heart... he did enjoyed singing and having fun on the stage yet they shut him down,” commented an admirer.
“the whole time JOHNNY keeps signaling for his mic thats why he’s so pissed and went backstage rightaway after WALK to fix it,” wrote another fan.
Some said Johnny is "allergic to lipsync," while others noted that the idol was "out of mood."
“JOHNNY literally go "i won't sing, the mic is not even working" and let the backtrack play instead of lip syncing bcs everyone will know anyways bcs you'll just know they when 127 sing live,” commented an admirer.
“man who is allergic to lipsyncing decided not to sing during the performance due to a broken mic (he's MAD) but damn johnny the man you're,” wrote another fan.
“me too i wonder at first why he's kinda out of the mood and later i noticed he keeps signaling for the mic and now he's backstage,” stated another fan.
