The only thing Kudo had known was violence.
From birth to adulthood, All For One's dark reign had overshadowed any hope in humanity and had quickly rotted from within.
At least, until All For One was permanently defeated and the light had been restored, giving way to a sense of humanity that had seemed lost.
Now that everything was over, Kudo had no fucking idea what to do.
Having created and been part of a rebellion against the nemesis All For One, and despite having aimed to defeat him, the light at the end of the tunnel had seemed impossible to obtain.
And now that it had happened, he didn't know what to do.
Meeting you wasn't in his plans either, and as a retired soldier, he didn't know if the quiet was completely peaceful or not.
It was as if he couldn't relax completely, the most natural consequence after years of being alert for the slightest movement in case it was something dangerous.
He hadn't lived a normal life until before meeting you, relaxing and settling down to live a quiet life was not as easy a task as it seemed.
But it certainly wasn't something Kudo regretted.
