Caged Revenge

Lin Wan’er’s beloved younger brother, Lin Chen, dies under suspicious circumstances at Beichen Military Academy. Though officially written off as an accident, she refuses to believe it and decides to enter the lion's den for answers. Cutting off her long black hair, Lin Wan’er enters the academy under the name Lin Shen. She regards everyone as a potential threat or target of investigation. And the cold, iceberg-like instructor Gu Yanzhi, once her brother’s instructor, becomes the first and most important suspect in her heart. Cautiously, she tries to uncover clues from him. Gu Yanzhi, meanwhile, observes Lin Wan’er from the shadows and slowly becomes drawn to the truth beneath her disguise—her kindness, her stubbornness, and her unyielding devotion to avenging her brother. In the end, the full truth is revealed. Lin Wan’er avenges her brother’s death, and she and Gu Yanzhi finally come together.
