At the concert, NU'EST W successfully performed several of their songs but ran into technical difficulties while performing ''If You".

The audio and the mic suddenly cut off in middle of Baekho's part. Aron, JR, and Ren, startled by the abrupt pause, immediately look over at Baekho. The members look confused while Baekho tries to continue on. 

The awkward situation was remedied by the fans. Instead of complaining or getting surprised by the audio malfunction, the audience helped the boys get back on track and continued the performance by singing along. 

NU'EST W responded with smiles and thumbs-up to the fans.

The audio came back on shortly after and the group was able to successfully complete their performance with the help of their fans. 

Many netizens touched by the fans' reaction, commented, "This is so sweet. I wanna cry", "It's a collaboration performance of L.O.?.E and NU'EST W~ ^^", "This is Daebaek", "OMG! So sweet."
