"'Don't wanna go back to work'... I guess people get lazier when they get old. Maybe you should start thinking about retirement, Hagane-san? Time sure fly by, huh. Bet you have a sore back, now? weak knees? How many times this week have you said the following: 'Kids these days... Back in my day––!' ?" Is she mocking him for no reason at all? Yes, she is.
The raw days of his youth might have been spent but that might’ve been best for everyone involved. It paid to have a chip on his shoulder during times of war, activity, political tensions running high; he was always ready to go and did his best despite his grievances.
Now there was no immediate threat to the country, his loved ones, his fellow shinobi or his community. Fun happened more often, life grew more comfortable, and he nestled himself into his burrow of sweet treats and laziness like a bunny set to hibernate.
Tenten was right, though. He was much older now, the laugh lines on his face were starting to deepen and the knit between his more often than not furrowed brow was there to stay. Moles sprouted from his face and neck and arms. What was once nicely defined muscle was now packed under the extra pounds of happiness he’d found in the quiet years of his hibernation.
He was 33 now, pushing 34, looking more and more like his father the longer he let his hair grow out and his mustache untouched.
“I’m not old,” Kotetsu sternly corrected her with a squint in his eye, “my back hurts, sure! My knees hurt, yeah! But old’s what happens to people when they give up on their hopes and dreams and let life happen to them instead of taking it by its reigns and doing whatever the hell they want.”
He sets down the stack of nagamakis and nodachis Tenten had somehow convinced him to carry from the stalls at the weapons festival.
“And I’m gonna do whatever the hell I want, including not work!”
Which was funny enough; he fell in love with helping Tenten run her shop. It was a great place for him to sell the weapons he makes with his own hands and he never would’ve guessed how fulfilled he’d feel teaching someone a few things about running a forge and the sacred art of weapon smithing.
