I Left All the Troublesome Matters to My Sister, Who Is Called Incompetent, and for Some Reason She Got Sick. Moreover, She Seems So Much More Competent

There is a girl in my house called Incompetent.

She is the girl who suddenly came to live in our house as soon as I turned eight years old.

Father suddenly said, “From today on, she’s your younger sister. Be careful in public.

At the time I didn’t understand what he meant by “just a younger sister” and I didn’t understand what he meant by “be careful in public,” but somehow I understood that it was okay to treat her roughly, even if I didn’t understand what he meant by that, just by looking at the way the adults were treating her.

I didn’t know what it meant to be “nice,” but I knew from the way the adults treated the girl that it was OK to be nice to her, even if I didn’t know what it meant. …… But I didn’t know what “nice” meant either, so I decided to leave the troublesome matter to the girl who had become my younger sister.

I was not sure how to handle the troublesome things, so I decided to leave them to the girl who became my sister. ……Well, basically the maids would do the troublesome things for me, so I continued to leave them to the girl who became my sister.

However, when I turned 15 years old,…… or maybe even before that in truth, I realized.

I realized that what I had been doing was a form of bullying,

So I decided to apologize.

I didn’t …… know that it would turn out to be quite different from what I expected.
