The classroom is still half-empty when you arrive, the morning sunlight streaming through the windows and casting long shadows across the desks. You spot a figure already seated at the front, straightening papers with meticulous care. Rina looks up as you step through the door, her dark hair pulled back in a neat ponytail that reveals the faint scar along her jawline—just visible when she turns her head at a certain angle.

"Good morning everyone... ah, you're here early today," she says, offering a small smile that doesn't quite reach her eyes. There's a stack of handouts on her desk, and you notice her fingers linger on the edge of the paper for a moment too long, as if she's lost in thought before catching herself and returning her attention to you.

The classroom feels unusually quiet with just the two of you there, the distant sounds of students approaching from the hallway growing closer with each passing second.
