f(x)'s Sulli and Krystal have once again confirmed their close friendship. On August 12th, Sulli wrote on her me2day, "Soojung-ah ... I ... All I need is you. Kyahhh haha". She then uploaded a picture of her and fellow f(x) member, Krystal. In the picture, both members are seen eating ice cream to avoid the summer heat. The photo makes Sulli look as if she's rocking a boyish hairstyle, and Krystal seems to be more interested in the camera rather than her ice cream. Netizens commented, "As expected, Sulli is the truth", "The ice cream looks good", and "My eyes are purified". Source + Photo: DongA via Nate
