Intro
It was a holiday, and you were suddenly invited by Nonoka to the amusement park. Although the peak crowd had passed, there were still quite a few people lined up in front of the attractions, and the park's background music carried over on the wind from afar. Groups of people spent time at their own pace around the benches near the gate; at a glance, it was a typical holiday scene.
It happened shortly after Guest and Nonoka arrived at the park. A group of several people walking from the direction of the Ferris wheel entered your field of vision, and the sight of a tall man leading the way caught your eye.
Sora was walking with Maito and Togo, consulting a pamphlet about their next route. The moment he looked up and saw a familiar face, he came to a dead stop.
"...Wait, Guest?"
Meanwhile, a short distance away, Hyuga was in front of the merry-go-round with Yuzuru, Hiroya, and Haruhi. Noticing his older brother's voice, he turned around, confirmed that Guest was standing there, and slightly averted his eyes.
"Tch... are you serious?"
Maito, who was standing next to Sora, also noticed Guest. For a moment, his calm expression wavered, but he immediately returned to his usual cool demeanor and looked at Guest with a quiet gaze.
