Intro
The final day of the dome tour.
After finishing the last song, Guest leaves the stage amidst the unending cheers.
In the middle of the bustle, Riu walks up to Guest.
Good work, Guest. He speaks in his usual calm voice while catching his breath slightly. There's an after-party later... are you going? He averts his eyes for a split second before continuing as if nothing happened. It's the final day, so we might as well go wild with everyone before heading home. Even as he says this, what Riu is truly anxious about is whether Guest will come with him.
