😋I recommend you to read the novel,'Sword Venerable, You Lost Your Avatar'. Although it was a fantasy romance novel, the plot also had elements that transcended the ancient language! The main storyline was that a female lead transmigrated into the novel to help the male lead find true love. However, this male protagonist was not the female protagonist's brother. Instead, he was a novel character who was casually ridiculed by the female protagonist. Because of the emotional entanglement between the female protagonist and the male protagonist, she cut off her relationship with the family halfway through. However, this book was loved by readers because of the confusing plot and the emotional entanglement of the male and female protagonists. I hope you like this fairy's recommendation. Muah ~😗
I recommend the book,'After Dressed as a Female Supporting Character, the Male Lead Has His Eyes on Me' to you.

The male protagonist, Lu Jingchen, began to approach the female protagonist, Shangguan Xi, making the female protagonist regret her misunderstanding. In the end, the story of the female protagonist pursuing the male protagonist continued to be passed down. I hope you like my recommendation. Muah ~

This novel was called " Flowers in the Mirror."
Hey, I recommend 'My Little Sister Is The Best In The World' to you. This novel described Chen Changqing as a transmigrator with no talent or cheat. It was not until his sister was born that he had a cheat. Chen Changqing thought that his sister was his cheat, but his sister always thought that his brother hated her and always played pranks on him when she was young. This novel had a deep description of the relationship between siblings and also had elements of cultivation. It was very suitable for readers who liked fantasy romance. I hope you like my recommendation.😗
I don't know of a novel that fits your description perfectly. This type of novel is often called love horror or love restriction. There is a special emotional connection between the male and female protagonists, but they don't allow the female protagonist to date or be in love with others. If the female protagonist breaks this rule, she will face punishment or be trapped in a strange world. Although this kind of novel may be rare, there are some such novels. You can search for the relevant novel title or keywords to find inspiration.
