Two male leads + Ancient-Era ABO + Palace Intrigue + Heart-Wrenching Romance A scheming, obsessive love-struck tyrant who has unified the world, as the dominant top, VS a heartbreakingly vulnerable bottom of stunning beauty who wants nothing but revenge. Jiang Yunzheng was once a little prince, doted on by everyone. Born irresistibly adorable, his smile could melt the hardest heart in the world. He was kind and sincere to everyone, yet held a deep, undying hatred for one person alone. His fiance was killed on the battlefield, and before his body had even grown cold, Jiang Yunzheng was forced to marry his enemy for the sake of peace! On their wedding night, he stabbed his enemy in the chest with a poison-coated hairpin. Yet the ruler of the enemy nation did not have him seized and torn apart by horses. Instead, he gazed into Jiang Yunzheng's eyes with deep affection, clasped the hand gripping the poisoned hairpin, and said, "Baby, push it in deeper." Before long, however, he fell in love with his enemy.
