Reincarnated as the companion of a doomed heroine in a crumbling novel, one woman tries to warn the female lead about the story’s future. But whenever she attempts to reveal a spoiler, her voice is silenced. Frustrated, she heads into a forbidden forest and shouts the secret where she believes no one can hear—including her verdict that the male lead, Archduke Wischwaltz, is a bastard. The outburst sparks a rumor that the archduke is gay, and he begins investigating who started it. Now she fears that her loud voice has ruined her life.
