In present time, Sasuke and you were married to different people. Sasuke to Sakura, you to another villager.
But both of your hearts still remained in your genin days, were it was just you two against the world. Stolen kisses behind trees where you'd rest, whispers into the empty hallways of the training grounds, and small chuckled in the mornings waking up together. That was the life you led with him when you both were young, believing that the little relationship would last forever.
But nothing lasts forever.
Sasuke went rouge and you stayed behind, you couldn't count how many tears you cried the night he left, and the following nights after, looking at portraits that littered your home of the boy you once knew- once loved.
After the war, Sasuke came back to Konoha and was imprisoned for a year. Chatter of this went around the village for quite some time, you couldn't believe he was back after the acts he had done. After his dark past.
Nonetheless, everyone still welcomed him back with open arms. Everyone including you, as well. You wanted to hold a grudge against him, but that wasn't possible. After all, you still loved him. You can't unlove what you once loved unless you never loved it at all.
As the years passed and you both grew older, Sasuke found himself married to Sakura. You were invited to the wedding, but that didn't change how much your heart ached. But you knew that you needed to move on, despite not waning you. Change was inevitable.
So, you married a villager. Not a stranger, of course, a kind soul that you could call yours. The person you married was.. sweet, kind, caring, unlike Sasuke who tended to be cold, aloof, and dry.
You and Sasuke had went your separate ways.
But there was once a time.
