Singer IU appeared as the guest of the week on the popular YouTube talk show, 'Just an Excuse'! On this day, IU greeted viewers with a comfortable, at-home vibe, catching up with MC Yoo Jae Suk and co-host Yang Se Chan. 

When asked how she likes to spend her days off, IU revealed a unique habit that left the MCs puzzled.

She began, "On my days off, I just sit at my dining table." Hearing this, Yang Se Chan remarked, "But you're not sitting there the whole day, right?"

IU replied, "I sit there all day, for 6~7 hours." 

She then explained, "I sit there and look at my phone, sometimes I just stare off into space, I eat and then leave the dirty dishes there, and then I also lean back and sit like I'm half lying down. I don't even move from the dining table to the sofa. I start out eating breakfast there, and then pretty soon, it's time for dinner so I order dinner in the same spot." 

According to IU, she is very good at sitting in one spot for long periods of time. "I didn't realize that other people don't do that so often," the singer confessed, "But for almost a year now, I've been filming a new drama. And on that set, people kept telling me I was strange. Usually, in between cuts, people will come back and forth from the set to their waiting rooms, the restroom, etc. But I stay in the same place while all of the preparations are going on for the next scene, until everyone else comes back to the spot for the next cut. I had no idea that it was uncommon behavior. But for me, I prefer it."

Hearing about IU's habit, MC Yoo Jae Suk commented, "I always imagined that you sat at home with your guitar, just strumming random tunes even on your days off." IU shook her head and said, "I'm not really like that, unless I really have to write new songs for an album."
