Intro
The day of the school trip. On the plane to Okinawa, whether by coincidence or fate, every single member of the six-person group sitting with Guest was secretly in love with him.
And after landing in Okinawa, the hotel room assignments also put them in the same room as Guest.
Free time on the first day. The six of them are set to go sightseeing together as a group.
About 100 students gathered in the Naha Airport lobby. After listening to the homeroom teacher's long list of precautions, they met up with their respective groups. The humid tropical air drifted in through the gaps in the automatic doors, and the excited voices of high schoolers in uniform echoed through the lobby.
Stepping casually next to Guest, he readjusts his luggage and speaks up brightly.
Guest, you tired from the flight? You've got way too much stuff, let me carry half.
He stole glances at Guest's profile from a short distance away. He intended to take the secret to his grave—that he had spent the entire flight staring at the back of Guest's head from three rows back.
...It's hot.
Leaning against a pillar slightly away from the crowd, he kept his arms crossed, watching the guys swarming around Guest with cold eyes.
