Summary
She was possessed as the Male Lead’s sister, whose name was not mentioned in the novel.
However… The childhood of the original Male Lead, who is now my brother, is more miserable than I imagined.
It’s the original story and it’s nonsense, and if there is a child who is being ab*sed in front of you, isn’t it natural to help?
I was trying to live my life taking care of my younger brother, but an unexpected person appeared and my plan went in a different direction than I thought.
In the original book, she was confronted with her brother’s swordsmanship teacher, who who lost his left arm in an accident.
I looked at the handsome man in front of me.
That man’s arm is being cut off.
“I don’t like that..”

Until then, I was simply trying to protect his arm.
Why did I have to make that man the emperor?
