On December 7, a new video was uploaded on IU's official YouTube channel.

One of the questions that Lee Jong-hoon asked IU was, "What kind of qualities do you think you lack of?"
IU answered, "Well, I feel like I'm not satisfied with any of the qualities I have except for the ones that are work-related."
Then, she asked Lee Jong-hoon, "Which of the qualities do you think I lack the most?"
Without hesitation, he responded, "I have to say that those are the qualities to be human as well as love for her own family."

She continued with an awkward smile, "That's probably why he thinks that way."
Lee Jong-hoon said, "She gave me such a hard time when I was little. I practically lived in hell."
IU playfully commented, "I'm sorry about that, but that's unfortunately how life works."
Born in 1997, Lee Jong-hoon is IU's only brother and is about four years younger than her.
