Trash of the Count’s Family

A brief description of the manhwa Trash of the Count’s Family:
When I opened my eyes, I found myself inside the story. [The Hero is born.]
The Birth of a Hero was a short story about the adventures of Choi Han, a boy, high school student who was transported to another dimension from Earth, and was born one of the continent’s many heroes.
I became a part of this novella, becoming the insignificance of the count’s family. This family controlled the territory where the first village visited by the protagonist of the novel was located.
The problem is that Choi Han changes after this village, and everyone who lived in it is destroyed by the assassins.
The big problem is that this stupid jerk I’ve become, doesn’t know what happened in the village, and gets confused with Choi Han, only to be beaten half to death.
– … This will become a problem.
I felt that something serious was going to happen to me.
But it is worth trying to make this new life better.
