Gu Ze was nobody—just a servant's grandson in the Duke of Elviss's household. But the Duke's kindness sent him to the best school on the Imperial Star.On his first day, his grandfather's parting words echoed: Take care of the young master. Repay the Duke's grace.So ten-year-old Gu Ze, trembling and tearful, approached the cold, silver-haired, golden-eyed boy who looked at him like he was nothing.He was terrifying. But Gu Ze stayed. Because that was his duty.Years passed. Gu Ze grew up—still a Beta, still a servant at heart. Until one day, the young master cornered him, leaned in close, and nearly sank his teeth into Gu Ze's neck.But there was no gland there."I'm a Beta," Gu Ze whispered, tears in his eyes.And Yano Elviss—the cold, beautiful heir of the Duke—smiled. A slow, knowing smile.A Beta? Or just someone hiding behind suppressants?He'd find out. And when he did, he wasn't letting go.
