This Time I Fight for Myself

He was originally the beloved younger brother of his mother and older sisters, but the son of his mother's best friend feigned depression, plagiarized his work, accused him of plagiarism, and framed him multiple times. This led to misunderstandings and resentment from his mother and three older sisters! That person even attempted to kill him in a remote area by running him over with a car. However, he didn't expect that he would be reborn. In this life, he no longer panders to his mother and older sisters out of humble familial love nor does he tolerate it.
