"It's something you've never seen," IU says, hinting to her next music video, which features BTS's V

A vlog featuring IU was posted on her YouTube page on December 25th, hinting at the release of her upcoming album. Her revelations increased supporters' expectations.

IU said, "It was so good, the tone and mood when I was shooting the MV," in response to a question regarding the music video. It was fantastic without any CG. Something not found in any of lU's music videos."

When the employees made the lighthearted comment, "Didn't you try to run away back then?" In a lighthearted statement, IU said, "I tried, to be honest. But my tire went flat. The funniest part is that when V-ssi's tire first went flat, I thought we should just flee, but then my car's tire went flat as well. I believe they placed something akin to glass on the location to prevent us from leaving."
