How did you get so cold?

The war was successful, and they won.
Sasuke returned to the village, and Naruto and Sakura both made their dreams come true.
They had families, and children and they were happy.

Even so, something has changed, the 7 Hokage is not what he used to be.

"Naruto, why are you so... cold?"

"You don't know, Uchiha?"

Sasuke Uchiha, broke the heart of the blonde, no, not only the heart, he had been destroying him for years, as well as the village and its inhabitants, until they finally crossed the border and the blond was never the same again.
He became cold, mysterious, and resolute, and lost the joyful honor that everyone knew and loved.

But the blonde hid from him an extremely important fact. A fact few knew.

And what if the secret that Naruto has been hiding for years will be discovered by his son and daughter of his 'friend'?

What if Naruto found out the truth about his wife's life?
What if he revives the most important person in the life of his would-be lover?
What will his reaction be?

What if he leaves the village and... abandons the position of Hokage?
He will abandon the village, its inhabitants, his wife, and...
He will live completely, elsewhere they pursue a normal, peaceful life with a loved one.
After all, this is what he always wanted
