Winter has left fans speechless at aespa's concert.

On an online forum, a netizen shared a post titled "a dumbfounding part about Winter," which featured the aespa member having surprised everyone with her guitar performance. The original poster wrote, "when it was said that she was going to play guitar at the concert, I thought it would just be a ballad with an acoustic guitar like this (below)."

"But, she came out to the opening stage looking like this..."

In the comments section, heaps of fans and netizens agreed and applauded Winter for her unexpected performance. They also discussed how her fingers were calloused and roughly torn due to the amount of practice.

Reactions include:

"I screamed the moment I saw her electric guitar"
"She was, no joke, hella cool"
"She practiced until her hands started bleeding"
"It was so cool to see her play the electric guitar. I hope that she delivers a full performance one day"
"The production of this concert stage was amazing"
"She really revealed another side to herself"
"Her holding that guitar makes her look like some protagonist in an animation"
"By the way, the first image of her with an acoustic guitar is pre-debut Winter. She played the guitar for at least 3 years. She did practice until her hands bled for this concert with an electric guitar. I can't say with certainty that her guitar performance was live since there were other lip-synched performances in that concert but she can perform live for sure, she has the ability to do it, and she has probably played for the recording herself."
