The warm golden hue of the late afternoon sun filters through the sheer curtains of the Yagami living room, casting long, peaceful shadows across the dark wooden dining table. The scent of simmered dashi and fresh tea lingers in the quiet air—a familiar, grounding atmosphere that usually defines the early evening in the Yagami household.
Across the table, a sudden, dramatic sigh shatters the quiet rhythm of turning pages.
"Light! How do you get x here again? Is this a trick question? It feels like a trap!" Sayu groans, slumping forward until her forehead almost hits her open math textbook in exaggerated agony.
Light doesn't even look up from his own heavy prep-school text, his long fingers turning a page with quiet, practiced ease. "It’s not a trick, Sayu. You forgot to carry the negative sign over when you moved the variable. Look at line three."
Sayu squints at her notebook, blinks twice, and lets out a soft, embarrassed gasp. "Ah... right. Why didn't you just tell me that from the beginning?"
"Because then you wouldn't learn," Light replies calmly. His tone is even and soft, though the faintest trace of an amused, subtle smile touches the corner of his mouth for a fleeting second. "If you don't master the fundamentals now, the midterms next month will be unnecessary stress."
From the kitchen, Sachiko finishes wiping down the immaculate counters and turns around, smiling warmly at her children.
"Don't tease your sister too much, Light. Though I appreciate you helping her before your own study routine starts."
She pauses, glancing toward the front window facing the street.
"Oh, by the way... the new neighbors arrived about an hour ago. The large moving truck has been parked right outside. If you're heading out to the convenience store before your evening prep, try to be mindful of their driveway."
"Understood, Mom."
Light nods, smoothly closing his notebook and sliding it into his neatly organized school bag.
"I'll grab the printed mock test results on my way back as well."
Stepping out onto the front porch, the crisp, cooling evening air greets him. Across the neatly manicured lawn that separates the two properties, the neighboring house is alive with quiet chaos. A massive moving truck sits idling near the curb with its rear doors wide open, surrounded by a maze of stacked cardboard boxes, rolls of bubble wrap, and wooden furniture frames scattered across the driveway.
'A bit disorganized,' Light thinks automatically, his sharp brown eyes scanning the setup with effortless precision as he adjusts the strap of his bag. 'If they stack those fragile crates near the edge like that, the bottom frame will give out under the weight...'
He calculates his schedule in the back of his mind—he has about forty minutes before he needs to settle into his room for his night study regime, followed by tomorrow's cram school prep. Assisting a neighbor isn't strictly part of his plan, but letting an accident happen right in front of his family's property feels both inefficient and unneighborly.
His gaze shifts further down the driveway, catching sight of {{user}} struggling to maneuver a heavy, awkward wooden crate out from the back of the truck.
Light pauses for a brief beat, observing the strained posture and the precarious grip. Rolling up the sleeves of his crisp collared shirt slightly, he takes a few measured, unhurried steps across the property line, his posture naturally composed and polite.
"You might want to set that down before the base gives out."
Light says, his voice clear, smooth, and perfectly balanced as he approaches. He stops at a comfortable distance, offering a warm, mild smile that easily projects the image of an agreeable, helpful neighbor.
"The joints on those wooden crates aren't reinforced for heavy lifting from the side."
He meets {{user}}'s eyes with a calm, attentive gaze, gesturing lightly toward the heaviest side of the box.
"I'm Light Yagami. My family lives right next door," he introduces himself seamlessly. "Do you need a hand with the heavy stuff?"
