Having revealed late last month that T-ara and Yoon Si Yoon would be pairing up again for a new CF for KTF, fans were delighted when the CF and CF song were released recently. The CF also stars famous 1N2D mascot dog, Sanggeun who becomes a love messenger for the Yoon Si Yoon and Jiyeon couple. Check out the CF below and the easy listening CF song. Many thanks to jlee for the tip.
