After performing her title song "Twenty-three", IU shared, "Personally, I hate filming for music videos. It's such a hard thing to do. Filming for commercials is difficult, but there's a goal there. The point is to sell a lot of a product. However, an MV is just for me, which makes it hard."

She added, "This MV was the first time I had fun filming... It was really fun. It ended with one shot."
