On April 13, f(x)'s Sulli posted a photo on her me2day account with the message,"Whose back is this?"

In the photo, Sulli is enjoying the sightseeing on a horse's back. Her face was hidden from camera and only her back was seen. It is the interesting experience of Sulli when f(x) filmed for MBC's show titled 'Amazing f(x)' in New Zealand, a show which showcased the cultural experiences that f(x) members go through.

Netizens commented, "Who else?, definitely yours", "The view is nice", "It looks like a magazine pictorial" and many more.
