Her performance continued to dominate online forums and discussions for weeks, but most people appeared to have missed the fact that she had a co-performer with her on stage. That day, former K-Pop trainee and Single’s Inferno fame Lee Si An also performed alongside Eunbi.

Since the performance, Lee Si An’s participation has not been much talked about. However, in a recent YouTube video, Super Junior member Shindong interviewed her, bringing out her unfiltered reaction to Eunbi’s performance.

Shindong started off strong, pointing out how all the articles talked about Eunbi only, even though she had shared the stage with Lee. “It’s hard to tell if you guys went on stage together,” he teased, making her playfully protest. Shindong pulled her leg, asking if she really performed on the same stage as Eunbi, to which Lee replied, “There’s even a fancam! People loved it so much that we even did an encore!”

Shindong then asked if the two had coordinated their outfits in advance or if Lee Si An had turned up at the venue completely clueless about Eunbi’s look.

Lee responded, revealing that even though she did see the outfit and the color schemes, she hadn’t seen the actual fitting photos. “She was way more ready than I thought,” she confessed, adding, “I did kinda get flustered.”

Shindong further teased her, saying, “It felt like you were going at it hardcore,” implying that she was trying to compete with Eunbi for the audience’s attention on stage.

Lee answered humbly, sharing that it was her first time on stage in seven years. “I thought I had prepared enough, but you know…Eunbi is just Eunbi.”
