On October 14, IU showed up at EUNJI's second solo concert 'HyeHwa Station' at Yonsei University, Seoul as a surprise guest.

On top of the beautiful harmony created by the two, their similar outfits made them look as if they are the members of the same group from the get-go.

EUNJI's fans at the site were moved by such kind gestures, since IU not only brought her own backup dancers to the concert, but also came up with many ideas to support her best friend.

It looks like EUNJI telling IU that she is a huge fan of her work at one music show in the past was the best thing that could have ever happen to them.
Meanwhile, IU is currently sweeping the charts with her latest digital single 'BBI BBI' released on October 10.
