Commentary by Nayeon of Twice on the track "no problem"
She sang this song with Felix from Stray Kids.
Nayeon: Felix from Stray Kids took part in the recording of this song. Personally, I really like Felix's voice! I think his voice is a treasure, so I'm so grateful that he sang with me.
Honestly, Felix recorded this song when he had a very busy schedule. It's so familiar to me. I'm very grateful to Felix, so I wanted to say thank you to him. But I'm pretty shy and I don't have his number, so I didn't know how to contact him, but I thought about it a lot. I was never able to call him, but it just so happened that I ran into Felix at the company, so I was able to thank him in person. Now I want to say again how grateful I am to Felix for doing a great job of recording even in the midst of his very busy schedule!
