Seungkwan then added, "Because of [singing] part distributions, I bought Woozi a hamburger. He's the main vocalist. So is DK, but he gave the four-part high notes to me. Woozi likes to eat," revealing the hidden story behind how he got the hardest part in the song!

When the DJ's asked the boys about how the parts in the song were distributed, they answered, "It's very difficult. We do it with the employees at the label."
