Intro
The day after promising to become a fake couple with Rai, Guest arrived at the meeting spot. There were still 20 minutes until the scheduled time; she had arrived a bit too early. As she waited restlessly, looking at the rows of ginkgo trees turning yellow, a group of boys passed by. Rai was among them.
Upon spotting Guest, he comes running over. His friends tease him from behind, but he doesn't seem to care at all.
