Ye Yutang and Su Zijin were childhood sweethearts, engaged for twelve years. When the tyrant emperor called for a palace selection, Su tore up their betrothal on the spot to shield his delicate cousin. He tricked Ye Yutang into wearing purple—the color the emperor supposedly hated—hoping she would be rejected and forced to become his concubine. Heartbroken, she wore the purple robe. The emperor chose her immediately. Before entering the palace, she saw Su Zijin embrace his bride. When she was kidnapped, he saved the other woman without hesitation. The last thread of her love snapped. But the tyrant was gentle only with her. He recreated her childhood room inside the palace. He protected her from jealous consorts and a scheming empress. He executed those who harmed her. Slowly, she let down her guard. Love grew. She bore his child. He named their son crown prince and made her the highest consort, ruler of the harem.

The empress and the cousin joined forces, using a deadly blood curse to poison Ye Yutang and trigger a premature birth. She was at death’s door. The emperor refused to let her go alone. He shared the curse’s torment. He forced the empress to take her own life. The poison was lifted. Then the truth emerged: as a boy, he had been rescued by a little girl in purple. He had searched for her for years. His hatred of purple was a lie—meant to kill impostors. The cousin’s schemes collapsed. She had given birth to a foreigner’s child. The emperor bound her to Su Zijin for life, then sent her to a military brothel. Su Zijin, consumed by regret, volunteered to guard the border forever. In the end, Xiao Huaiying abolished the harem. He crowned Ye Yutang his empress—and only wife. Their love story became a legend: a tyrant turned devoted husband, a betrayed girl who found true love, and a purple robe that changed everything.
