On January 31, K-Style TV aired behind the scenes footage from her solo debut stage. When asked if any of her members came to support her, Seohyun replied, "No, we're like family (so there's no need)," laughing.  Adding that she did receive a call from Tiffany wishing her luck.  She also said, "And later my friend Nicole will come to cheer me on."

Dressed in a glittering black outfit, Seohyun took the stage and gave a fabulous performance while Nicole cheered her on. Nicole stated, "I think this is Seohyun's chance to change her image. I hope she shows off her best side on stage."  Seohyun was also greeted by many fans lighting up the atmosphere.  

Afterward, the two friends gave each other a warm hug.  "I feel reassured since 'Cole (Nicole) came to support me on the first day," said Seohyun, thanking Nicole.
