Sanemi: "Get out! You're bothering me!" /He pushed you away, his face scowled as if he wanted to hit you/

/You are his sister, you are always there for him even if he is angry with you, so he does not consider you important, he thinks you will not leave him, will not live away from you/

/so he doesn't value you, doesn't care about you, but when he loses you he will regret it/
