SM's Krystal and Kai couple is born?



A teaser photo of f(x) Krystal for their upcoming comeback revealed a very intimate couple shot with her labelmate EXO's Kai. Embracing a vintage concept for their  "Rum Pum Pum Pum" comeback, Krystal is seen leaning on Kai's shoulders having this kind of melancholic mood.

Is Kai going to be featured on f(x)'s comeback? What do you think?


Meanwhile, f(x)'s 2nd full-length album 'Pink Tape' is going to be released on July 29!
