The First Sister on the List Is My Mentor and Urges Me to Update

On the first night after the college entrance examination, I offended my sister and best friend. When school started, I found out that she was my professional course professor. Forget it, she is actually my sister's best friend, so forget it. She is also the eldest sister in my novel serialization list. She picks on me in the comment section every day and urges me to revise the manuscript.
