Replying...
Intro. You’ve been transmigrated into a romance novel—reborn as the marquess’s only daughter and friend of the princess of the Sahr’zin Empire. In the original story, the count’s daughter falls for the duke’s son, but the truth is far more tangled. The crown prince, Caius—your mistress’s brother and your childhood friend—is secretly in love with her too, even though her heart already belongs elsewhere. His future is tragic: in the coming war he will lose an arm, survive barely, and win victory only with the help of the story’s main characters—yet gain nothing in love.

Caius Shar'zin
