This is a fun, chaotic scenario! Given Shikamaru's established personality (genius-level intellect, extreme laziness, and a strong sense of duty once motivated), his younger self suddenly abandoning his primary trait (laziness) for a mission (finding Temari) would be truly startling to his parents.
Here's how that chaotic morning would likely unfold:
The Unprecedented Disobedience
It's a typical morning in the Nara compound. Young, ten-year-old Shikamaru, still pre-Chūnin Exams, is likely slumped on the porch or gazing at the clouds, already bored with the day. His mother, Yoshino Nara, a formidable woman who manages the entire Nara clan household and its famously lazy men, issues her usual command.
Yoshino: "Shikamaru! Don't just sit there like a slug! The garden needs weeding, and those laundry scrolls won't put themselves away! Get moving!"
Normally, this would prompt a protracted groan, a theatrical sigh about the troubles of life, and a half-hearted attempt to negotiate his way out of the chore.
But this time, the Shikamaru who remembers the future snaps to attention. He knows exactly what he needs to do, and time is of the essence—he's got a future wife to track down, and a whole lot of political drama he can probably avoid if he gets this right.
Shikamaru, fueled by the sheer motivation of avoiding future complications and getting straight to the good part of his life, leaps to his feet with an uncharacteristic burst of energy.
Shikamaru: (Not even bothering to groan, just grabbing his headband) "Sorry, Mom, can't! Gotta go find the love of my life! Catch you later!"
He doesn't saunter; he sprints out the door and through the garden, moving faster than he ever has for anything not involving immediate mortal peril.
Yoshino and Shikaku's Reactions
The sheer speed and content of the declaration would leave both of his parents in a state of stunned confusion that breaks their usual routines.
Yoshino Nara (The Iron Fist)
Reaction: Immediate, furious disbelief, followed by existential concern.
Yoshino would be so shocked by the lack of groaning and the sudden burst of energy that she'd momentarily forget to be angry. The declaration itself would then hit her like a surprise kunai.
* Stunned Silence: She'd stand over the unattended chores, frozen, holding the laundry basket. Did my lazy-ass son just sprint? And for what?
* The Interpretation: The words would register, and her brain would short-circuit. The love of his life? He's ten! Did Ino put a strange jutsu on him? Is this a mission? Is he hallucinating?
* The Panic: She would rush to the porch, peering out at the road where her son vanished. Her voice would be high-pitched, a sound Shikaku rarely heard: "Shikamaru! Get back here and finish your—! Shikaku! Something is seriously wrong with our son! He just ran off to find some 'love of his life'!"
Her primary concern wouldn't be the chores (though they'd still matter), but the unprecedented break in his nature. This level of motivation, for something so emotionally charged, would be a five-alarm fire in the Nara household.
Shikaku Nara (The Strategist)
Reaction: Quiet, deep astonishment, followed by rapid, strategic calculation.
Shikaku, a man known for being unreadable and unflappable, would likely be observing the clouds or reading a strategy scroll nearby. He would witness the entire event.
* Observation: He'd see the instantaneous, non-lazy movement from his son—an event so rare it defied physics. He'd hear the clear, motivated declaration.
* The Pause: He'd put down his scroll, his brow furrowed in a way that suggests he's solving a complex equation. My son, who finds breathing taxing, just achieved mach speed to find a significant other. Why the sudden, profound motivation?
* The Analysis: Shikaku would conclude that this couldn't be a childish whim. It would have to be either a secret, high-stakes mission disguised with bizarre words, or his son has developed a new, powerful mental affliction. Knowing Shikamaru, the truth is likely somewhere in between.
* The Conclusion: He'd calmly address his panicking wife: "Yoshino. If Shikamaru is motivated enough to move that fast, whatever he is searching for is of critical importance to his future well-being. Or it's a very pretty cloud." (He'd add the last part to maintain his façade of laziness). He wouldn't chase him; he'd recognize that his son, for the first time, had a clear, self-directed strategy, and he'd trust him—albeit with a profound sense of confusion.
Final Thought: The day would be marked by an absence of the usual noise and a bizarre cleanliness. Yoshino would finish the chores herself, muttering about the audacity of a ten-year-old running off for romance, while Shikaku would spend the rest of the day trying to predict which of the neighboring villages contained the "love of his life" that could overcome the insurmountable force of the Nara clan's genetics.
