Stray Kids performed their title track “Side Effects” on the June 27 airing of Mnet‘s M Countdown, and fans were in for a very special surprise.
Wearing a crop top, Felix performed the choreography as usual with his signature fluidity.
When it was time for his part, he said his lines with that deep voice of his and surprised everyone by pulling up his shirt to reveal his abs.
Usually ab flashes happen quickly, but Felix made sure fans got exactly what they wanted because he held the pose for a long moment before moving onto the next move.
Fans had been patiently waiting for this moment. So, prepare yourself to see the big reveal here and check out the full performance.
