The train station bustled with ceaseless activity, alive with movement. In the spring of her twenty-third year, An Xiaoyi finally received the acceptance letter from that university. Agents, operatives, wielders of power… This was, in truth, a violent institution dedicated to opposing the vampires. He became a professor, teaching foundational knowledge of supernatural abilities and the history of vampires. Filled with anticipation and a deep sense of responsibility, he trained his students to bolster humanity’s strength against the bloodkin—all while searching for clues about his long-missing parents. The problem? He had another identity—she was, in fact, a vampire herself. Even worse, on her very first night in the dormitory, a mysterious vampire woman suddenly kissed her, claiming to be her lover. An Xiaoyi remained outwardly unfazed and struck a deal with the woman: in exchange for information about her parents, she would help the woman “conquer” her. After all, there was no way this woman knew her secret. But gradually, she began to suspect that the cunning, domineering woman was only acting… By the time she realized the truth, it was already too late—she had fallen deep into the trap.
