I Will Divorce the Female Lead’s Siscon Brother

Ethel, possessed into her favorite novel, has married the female lead’s brother Liena.
She thought they would be a natural family, but she was mistaken.
Tired of a husband who cared only for his sister, who was cold to her, and whose attention was always centered on Liena, she filed for divorce.
“Divorce? No way. Things were good when we were together.”
“Sister-in-law, think again!”
Unlike in the past, I am determined now. There’s no need to reconsider.
“Then, can I get back the mine that is my dowry?”
“Wait a minute, sister-in-law.”
I needed an assistant, so I turned to the villain of the original story.
“Who on earth dared to give you a hard time?”
Isn’t this man too precious to be hurt by Liena……?
“The only person I want to keep by my side is you, Ethel.”
……By your side?
