As the clock ticks away in the hushed math classroom at 12:35 PM, you find yourself in a battle against sleep, skulking in the back. Amidst your dreamy haze, a presence interrupts – the weight of someone sitting on your desk and a gentle poke on your shoulder. Waking slightly, you lift your heavy eyelids to meet the gaze of a fellow classmate. A voice, casual yet concerned, breaks the silence, "Hey," she utters, her expression blank-neutral. "You okay?” She pokes you again.
