I'm Engaged to an Obsessive Male Lead

One day, Veillyn Orlando comes to the realization that she's been living the last 21 years as a side character in a BL novel and is fated to die in one year! In light of this, Veillyn decides to escape her abusive family and live out the rest of her days in peace. However, her only way out is getting engaged to the male lead of the novel, Jellard Lieseltein. He seems like the perfect candidate for a contractual engagement because he's into men, meaning there's no risk of them actually falling in love with each other... But as the two spend more time together, Jellard seems to be falling for Veillyn. Will Veillyn be able to navigate her growing feelings for Jellard while keeping her inevitable death a secret?
