Although it wasn't the area I had hoped for, I was in a seat close to the sub-stage, and when they came near during the final wave, they were very close. However, performances on the sub-stage were always completely obscured by the background LED screen descending. I understand that such stage configurations are difficult to predict and cannot be helped. Especially given the poor transportation options for returning from Incheon Inspire Arena, the round-trip shuttle bus was extremely helpful.
