Chapter Text
The resentment did not come overnight.
When Otou-sama told him that two children were going to come and live with them, he wasn't sure how to feel.
Okaa-chan didn't like it. Okaa-chan and Otou-sama even had a fight over it. Okaa-chan usually didn't fight with Otou-sama.
He didn't understand why she would do that. One of them was still a baby and the other was two years younger than him. He thought that maybe, she was angry over the additional work she had to do now for them. He understood that. But he also understood that the two of them didn't have their parents anymore. They had to be sad.
And then the girl screamed at Otou-sama and he slapped her and grounded her for a week.
He thought she was silly for doing that. He would need to explain the rules to her so she would never scream at Otou-sama again. After her grounding, because she needed to understand why she was being punished. Maybe, if she understood on her own, she wouldn't even need him to explain anymore. That would be best.
To his surprise, she did.
Otou-sama took him and her training after that. He was excited. He could show her what he was training and maybe, he could even teach her after she watched him.
But Otou-sama didn't let her watch. He let her spar with him.
He'd wanted to go easy on her. To let her have a starting experience different from what he remembered from his own harsh lessons with Otou-sama. He really wanted to be a bit like an older brother to her.
Until she opened her eyes and he saw nothing but red.
Otou-sama liked the red in her eyes. He talked to her, about her, compared him to her and did. Not. Stop. Not that day. Not the days after that.
Duty. Representing the clan. Prodigy. Even though she is a girl.
Keep up with her. Do you want to be left behind?
He hated hearing this. But Otou-sama wouldn't stop. So he worked harder. Maybe he would stop once he caught up with her.
He never did. She was always faster.
Techniques. Knowledge. Graduation.
Always faster.
The resentment did not come overnight, but one day, it was there. And he couldn't shake it off.
