It could be a family drama. Since it involves a sister, there are likely to be family - related issues, emotions, and conflicts that are typical of this genre.
I'm not sure specifically as there could be many novels with such a title. It might be about a hidden relationship between sisters, perhaps some secrets that are gradually uncovered regarding their family, past events, or personal lives.
A 'secret sister novel' could be about a hidden or unknown sister relationship. It might involve themes like family secrets, sisterly bonds that are suddenly revealed, or the impact of a long - kept sister relationship on the characters' lives.
Well, one interesting point could be the relationship between the characters. Maybe there are complex family dynamics or a special bond between the sister and other characters in the novel.
Since I haven't read it, I can't say for sure. But likely the sisters would be main characters, perhaps their parents or other family members could also be important characters in the story.
The secrets in the novels of Qing Yu Nian involved the secrets of the Temple and Taiping Courtyard. The temple was an important place. It was described as a building with black stone walls and light gray eaves. There was a weathered plaque on the door, which contained the ruins of the last civilization of the previous era. It was similar to artificial intelligence and stored the entire process of the previous world from birth to death, including the most advanced weapons and high-tech equipment of mankind. There was a forbidden door at the bottom of Taiping Courtyard's lake. It might be Ye Qingmei's laboratory. There might be modern high-tech equipment inside. The specific details were not explained in detail, but it was certain that these secrets were related to high technology. Ye Qingmei had escaped from the temple. She had taken a Barrett and the intelligent robot Wu Zhu with her. In general, the secrets in the novels involved high-tech weapons and the military science and technology museum of the ruins of civilization.

I hope you can find a novel you like among these recommendations.
Typically, the main characters would be the two sisters involved in the secret relationship. There might also be their parents or guardians who are somehow related to the secret.
