The Second Male Lead is Actually a Girl

I thought I was a non-existent extra, but they say I’m Duke ‘Rosenta Estella’ in the novel.No wait, Rosenta is a secondary male character?Wasn’t he a man?“Vivian, are you still asking Rosenta to tie up your hair?”“Huh? What does that matter?”Why are the male lead and the villain fighting over me?!The crown prince, who was originally described as a tyrant, grew up smiling and the wicked woman, Vivian, became a rabbit-like girl following me around.But the biggest problem is…“Please put a leash on me.”The obsession of the yandere character in the original work is directed toward me.Why is everyone doing this to me?!I’m just a secondary male character in charge of heartbreak!
