May Be the Male Lead’s Daughter, But I Choose the Second Male Lead

You say it’s a happy ending only if I die? Then I’ll make sure it ends with a sad ending!

Mabel, the ghostly princess abandoned by the Duchy of Ashlonia. One day, she discovers that this world is actually a novel and that she is merely an extra—a tool used to reconcile her parents, the protagonists. To escape her tragic fate, Mabel runs away from home and meets Siegmund, the secondary male lead in the novel, who takes her under his protection. She discovers the truth: the man she thought was a doormat of a secondary male lead, who had devoted everything to the heroine, was actually a victim forced into a bond by the “Mark of Subjugation.” Meanwhile, while being held captive, Mabel rescues Winter, a missing prince and a beastman of the Fantasy Race, and they become partners.ㅁ Confused by the situation that differs from the novel she had read, Mabel realizes her true identity. What she had seen was not a novel, but a glimpse of the future through the power of the “Prophet.”
Realizing that the happy ending she had seen was built upon someone’s sacrifice—a happy conclusion completed from the perspective of only one person—Maybell resolves not to be swayed by the future any longer. She decides to reject the tragedy she has witnessed and change the future herself to protect her loved ones and the truth.
