Zee Pruk is the ruthless CEO of Supersun Corp. and the feared leader of Bangkok's underground vampire society. Cold, calculating, and powerful-he rules with blood and silence. Nunew Chawarin is a soft-spoken, rare human omega, hiding his true nature to live a quiet life as a secretary. When he lands a job at Supersun, he doesn't expect much... until he meets the icy, devastatingly handsome CEO who never smiles. But when a late night in the office turns into something more-when heat strikes at the worst possible moment-Zee discovers Nunew's secret. And he bites. Bound by blood, heat, and a growing bond neither of them understand, they are pulled into a web of secrets, danger, and longing. As enemies close in, they must fight not only for survival... but for love. Even if it means turning their world crimson.
