On December 21 installment of 'Radio Star,' G-Dragon stated, "I think I was a bridge for them. I recommended Min Hyo Rin -- who was a friend of a friend -- for Taeyang's music video because I thought she would be suitable for the role. Apparently, Taeyang also had her in mind. I visited the MV making site and Taeyang was smiling ear to ear. It's a sad song, but when he was hugging her, he looked so happy." 

The group's leader also revealed that he is the official dating coach for Taeyang. G-Dragon said, "When Taeyang has an argument with his girlfriend, it's written all over his face. He'll sometimes ask, 'What do I do in this situation?'"
