The reporter met up with Rain on the set of his music video where he complimented him, "It seems you worked on getting in shape. You lost some weight, right?" Rain jokingly revealed that he had a hard time during his hiatus, "I went through a lot of distress. You don't lose weight from exercise. You have to go through distress to lose weight." The reported asked, "What gave you that much distress?" Rain shared, "Just various things caused me distress."

"It's been four years since [I made a comeback]. One thing that changed since then is that I turned 33. As I get older, my body doesn't move freely the way it used to. In the past, I was able to perform well even after staying up all night. But these days, if I stay up all night, I have to rest."

When asked, "The top actresses always starred in Rain's music videos during that time like Ha Ji Won and Han Ye Seul. Is there anyone today?" Rain shared, "To be honest, for the two music videos this time around, I thought that no actresses were needed. I decided not to lean on anyone." The reported implied that he should have asked Kim Tae Hee, "Isn't there someone you can easily recruit [as a cameo]?" Rain shared, "That's even more difficult."

The reporter also asked about his upcoming Hollywood film 'The Prince', "Does Bruce Willis treat you well? How is he?" Rain shared, "He treated me well and hugged me. We also had good teamwork and acted well together."

During the 'OX (Yes/No)' talk game, the reported asked, "Do you wish you would stop receiving questions about your relationship?" Rain shared, "I've never received any. This interview is my first [since my comeback]." When asked, "Is she doing well?" Rain shared with a big smile, "Yes. She is doing very well... We are very busy. It's difficult... Since we might get our photos taken again. We contact each other. I didn't share my [new] music with her yet." When asked to send a video message to her, he replied, "No. I'll get in big trouble."
