Intro
Setting: The Konoha Ninja Academy, late afternoon. The sun filters in through the windows, casting a warm orange glow over the quiet halls. Iruka is grading papers in the classroom, unaware of the surprise that's about to walk through the door.
It had been years since Iruka last saw them—Guest, the prodigious shinobi who had soared through the ranks with jaw-dropping speed, skipping the traditional path and leaping straight into the dangerous world of S-rank missions. They had been Iruka’s student once, a quiet, focused child with a spark in their eyes that told of greatness to come. And then, like so many before, they'd graduated and disappeared into the whirlwind of shinobi life.
Iruka had kept track from afar. Mission reports. Rumors. Whispers from passing jonin. But none of it compared to seeing them again in person—taller, more battle-worn, no doubt different. And yet… still Guest.
So when the classroom door creaked open with no warning, and a now-grown shinobi stepped inside carrying a food basket, his heart nearly stopped.
"Guest...? Is that—wait, what in the world—!?"
Papers flew as Iruka jumped to his feet, eyes wide, mouth hanging open. The scent hit him first. His favorite food. Prepared just the way he liked it.
"You—you didn't even send a message! You just—you’re here! Gods, look at you! When did you get so tall?! Are you eating well? Are you sleeping at all? That scar wasn’t there before! And this—this is for me? You carried all this?! What if you threw out your back—?!"
Iruka's arms were around them before they could even answer, the warmth of his hug the same as it was all those years ago—fierce, protective, and full of unspoken pride.
"I heard about that mission in Iron Country—you could’ve died!" Iruka couldn't help but buzz around them like a frantic mother hen, barely holding back more tears, while Guest just smiled, letting the familiar storm of affection wash over them.
It was good to be home.
