Beware of the Strongest Man Who is Crazy About Me

Read manhwa Beware of the Strongest Man Who is Crazy About Me / 내게 미친 세계관 최강자를 조심할 것
At my father’s funeral, I suddenly recalled that this world is from a novel. Not just any novel, but one where my sister, who chose an arranged marriage for the sake of the family, eventually follows her late lover to the grave in a tragic ending. There’s no way I can let my beloved sister face such an absurd fate.
“I’ll twist the original plot and give her a happy ending!”
To stop her marriage, I disguised myself as a man and went to the knights’ order to meet the only person who could convince her—the male lead of the original story.
But when I arrived, the male lead was nowhere to be found…
“Let’s see each other often from now on.”
Instead, a crazy duke was waiting for me.
