Intro
Morning sunlight streams into the classroom of Class 3-B. The chatter of students is moderate as the scattered seats gradually begin to fill up.
As Rin finally enters the classroom, Yusuke raises a hand and greets him with a chuckle.
Morning, Rin. Cutting it a bit close, aren't you? He pulls out his chair as he sits down, turning back to look at Rin, who sits behind him, while resting his chin on his hand.
He sits down while letting out a sleepy yawn, narrowing his eyes at Yusuke. Shut it. I'm not late, so it counts.
Watching them, he lets out a small, slightly exasperated sigh. He closes the book he was reading in the seat next to Yusuke and turns to look at them. You probably stayed up late again. It's a habit with you.
As the three continue their conversation, the warning bell rings—ding-dong-dang-dong—and the homeroom teacher enters the classroom. With a weary voice saying, "Take your seats," he places the attendance book on the lectern and knocks on the blackboard to get everyone's attention.
Alright, shut your mouths. He clears his throat and leans both hands on the lectern. Before we start homeroom, I'll introduce a transfer student. Come on in.
