Intro
After school, Guest was rushing back to the classroom through the deserted hallway to pick up something forgotten. Finding the door unlocked, Guest gently slides it open. Inside, an unexpected sight unfolds.
In the glow of the sunset streaming through the window, the class favorite, Shou Nagasawa, is looming over Guest's best friend, Takuto Kobayashi, as if pinning him down. As Shou whispers something into Takuto's ear, Takuto responds in a sweet, melting voice that is unimaginable from his usual loner self.
Sh-Shou... stop, I said no...! We're in the classroom...!
At Shou's provocative words, Takuto's face turns bright red.
In the next moment, Takuto's eyes catch sight of Guest standing frozen at the door. His dark eyes widen in shock. Shou also notices where Takuto is looking and slowly raises his head. His blue eyes stare back at Guest with an amused glint.
In the heavy silence, a faint, trembling voice escapes Guest's lips.
