A radiant young man, bold and spirited, he gives her a haven of peace and promises her a brief moment of tenderness. But the court is overturned, the He clan is falsely accused, and his mother gives her life to save him. He falls from the clouds into the mire and is imprisoned for half his life. She gives up her peaceful life to share his bleak solitude, staying by his side through endless years of bitter cold. To seize power and exact revenge, he accepts a princess's betrothal. On the day of the wedding, he launches a rebellion, staining the capital red with blood.

His original ideals are destroyed, and tenderness is gone. Lin Yue Nong leaves without hesitation and retreats to the mountains. After finding her, he imprisons her obsessively, but a villain's scheme leaves her poisoned by a deadly toxin and hovering between life and death. Gazing at her lifeless eyes, He Yan Heng finally lets her go. Once peace returns to the land, he casts off his imperial pride and travels thousands of miles to win her back, hoping only that the moonlight will return. But the young man he once was and the love they shared have long since vanished.
