Kim Woo Bin said, "I am a fan of G-Dragon. He dances and sings really well. His fashion style is also very cool. I think of him as someone who dresses himself up really well. If I were to collaborate with G-Dragon, I would like to be cast in his MV if, from G-Dragon's point of view, I wouldn't get in the way of his song and he thinks I'd be good for it."
In addition, he chose CNBLUE's Jonghyun as the actor who makes the biggest impression. Kim Woo Bin said, "I first heard today that Jonghyun wants to act with me. I really enjoy the time we spend acting together. I feel like he's my kind and warmhearted younger brother, which makes me happy. We talked a lot about Jonghyun and our work."
