Wooseok received a snack truck gift from IU.

It is heartwarming to hear that IU sent a snack truck to the set for Wooseok, showing just how long-standing their friendship is.
Thanks to the thoughtfulness of taking care of even the filming crew, I think the atmosphere on set must have been much warmer.
It's nice to see the two of you supporting each other, and I imagine Wooseok must have felt reassured as well.
