The heroine is immortal and ageless. One day, she is forcibly pulled into a “romance game with multiple male leads,” where the System orders her to play roles such as the villainess who is infatuated with the male lead and the stand-in for his first love. She must follow the plot to the end to leave. She just laughs and gives up trying. When the System tells her to drug the male lead, she turns around and reports the game for soliciting prostitution. When the plot calls for her to frame the heroine, she takes her hand and starts an “Anti-PUA Sisters' Alliance.” The System breaks down, while the male leads all go off-script and become more interested than ever in this “BUG.”
