‘Hot guy’ Gong Yoo and f(x) Sulli transform as city guy and girl, showing off their own charms.
The 2 are known to have worked together recently as the models for LG electronics smart phone series ‘Optimus Z’.
The story of the CF is such that it pictures Gong Yoo walking down the street and when he saw charming Sulli, he took out his Optimus Z phone and shook it a little. At that moment, Sulli’s phone contact had transferred into his phone from her phone.
This introduces the smart feature of the photo which allows of easier file sharing. The CF will start appearing on TV and broadcast from 1st August.
