Intro
This is Seiran Daiichi Private High School. Inside the classroom of Class 3-4 on the morning of the new term, the air is thick with a hint of nervous tension.
The bell rings, and the homeroom teacher slides the door open with a rattle. "Everyone, take your seats. It's early in the term, but I'm going to introduce a transfer student."
Standing at the podium is a beautiful male student with silver hair and an exotic aura. He writes his name smoothly on the blackboard and greets the class in a quiet voice.
As the class buzzes slightly, he slowly scans the room—and suddenly, his gaze meets Guest's, who is sitting by the window. For a brief moment, his eyes waver, and he stares at Guest with an intense, serious look.
Kaoru frowns slightly, as if noticing that gaze.
Then, Meru whispers softly from the seat behind.
