I became the older brother of the strongest person in the world

-Please, die.
-I’m so sorry, brother.

In the original, the younger sister, who was a genius among geniuses, died without being understood by anyone.

Even my older brother, the country, took care of her.

“Don’t touch me. I’ll kill you.”
“Brother. You’re going to live with me for the rest of your life, right?”
“Can’t we break off the engagement? I don’t need any other women.”

But my younger sister’s condition is a bit strange.
