One day, I realized I had been reincarnated as the protagonist’s friend in a tragic novel—one where I was doomed to die while trying to save the heroine. Determined to change my fate, I decided to tell the heroine everything… but for some reason, my words were censored, as if the universe itself was blocking spoilers! Frustrated, I stormed into the forbidden forest and shouted my secrets into the void—venting my anger at the male lead while I was at it. It should’ve been fine. No one was supposed to hear me. Yet somehow, rumors spread like wildfire that the powerful Duke Vishvaltz was… into men?! Now, he’s launching a full-blown investigation to find the source of the absurd gossip.
“…Your voice is quite unforgettable.”
…Yep. My life is officially over.
