This was not Naruto's era yet. By the time Naruto became Hokage, it would be perfectly normal for someone from Sunagakure to marry someone from Konoha.
But in this era, ninja from every village married only ninja or civilians from their own village.
Marrying someone from another village was impossible.
So when Pakura realized she might not be able to keep her feelings in check, she made a difficult decision.
She would make Uchiha Yin hate her.
Sara was Uchiha Yin's woman. If Pakura tried to kill Sara, Uchiha Yin would surely hate her to the bone.
He might even hold a grudge against her forever.
Then the two of us could never be together, could we?
Then I could finally give up, couldn't I?
As for whether she could actually kill Sara, Pakura knew she had no chance with Uchiha Yin watching.
But showing that she intended to kill Sara would be enough. Enough for Uchiha Yin to condemn her.
After struggling with herself for a long time, Pakura finally attacked Sara with everything she had.
Clearly, her plan had worked.
Uchiha Yin was furious.
Yet Pakura felt no joy. Instead, a chill settled deep in her heart.
The cold look on Uchiha Yin's face made her feel colder still.
Pakura felt sick.
The thought that Uchiha Yin might treat her like a stranger tore at her heart.
But wasn't this for the best?
Break free before I fall any deeper!
Smack!
Uchiha Yin slapped Sara's pert backside.
"Do you know what you did wrong?" Uchiha Yin asked her sternly.
"Ah!" Sara's first instinct was to protest when he slapped her.
But one look at his dark expression, and she no longer dared to talk back.
"I was wrong," Sara said, lowering her head.
"What did you do wrong?"
