I've been Proposed to by a Villain

Following her transmigration into the world of a novel, Regina Blois is acutely aware of a terrifying certainty: she is fated to meet her end at the hands of the unhinged Duke Arsene Graroy after accidentally witnessing him brutally murder a political enemy of the empire. Desperate to escape this gruesome destiny, she takes every possible precaution to avoid crossing paths with him. Despite her meticulous efforts to rewrite history, fate intervenes, and she finds herself once again witnessing the duke commit the very same horrifying crime. With her presence exposed, Duke Arsene possesses every logical and malicious reason to silence her permanently to protect his dark secrets. Yet, against all reason and the expected course of survival, the dangerous duke completely upends her expectations. Rather than raising a blade to end her life, Arsene offers her something entirely unthinkable—a proposal of marriage.
