On September 22, Crush sat down for an interview ahead of the release of his new single 'Rush Hour' featuring J-HOPE.

Crush responded, "J-HOPE and I go back a long way. We've always spoken about music to one another. When I was getting ready for this single, I found some similarities between what I want in music and what J-HOPE wants in music."
He continued, "So, I decided to ask J-HOPE if he wants to work with me. He ended up featuring in my song as he said yes to that. I genuinely believed that this song went well with J-HOPE that I was so glad that he agree to feature in it."

Crush said, "While J-HOPE was recording the song, he didn't even go to the restroom. Even though he was showering with sweat, he was like, 'Hyung, let me do this part again. I can do it better! Let's go it one more time!' As I saw him work so hard like that, I came to have great respect for him. I thought to myself, 'Oh, I see why he's at where he's at now.'"
The singer resumed, "J-HOPE joined 'Rush Hour' music video as well. Thankfully, he was really up for it. Because there were lots of scenes where I had to dance, I was extremely exhausted throughout our shooting. But J-HOPE gave me so much energy by my side."
He added, "I also felt thankful to J-HOPE for monitoring all my scenes with me, and coaching me."
