When Jiang Chengyue was fourteen, the Xijue invaded the northern frontier. Her father died in battle, and her elder brother fell into a coma after being poisoned.
After turning the tide of the battle single-handedly, she was poisoned and hunted down. She lost her memory by accident and was rescued by an old woman.
When the old woman later passed away, Jiang Chengyue and Xiao Kui were left to depend on each other.
By chance, she saved Prince Qin, Xiao Yunmo, who had also been poisoned and was gravely injured. A further accident made the two of them husband and wife.
When Jiang Chengyue was three months pregnant, Xiao Yunmo took her to Shengjing. Only then did she learn that her husband was none other than the renowned Prince Qin of Great Zhou.
Though they had exchanged vows before Heaven and Earth, once she arrived at Prince Qin's residence, she became a nameless woman with no standing: Madam Su.
She felt lost, wronged, and helpless. But for the sake of her unborn child and the man who had already captured her heart, she stayed by his side without regret.
Then Xiao Kui was unjustly killed, and her premature baby died. She no longer had any desire to live.
Yet even after she willingly fled the prince's residence, the people behind it still wouldn't leave her alone.
When she fell from a cliff and learned the truth about Xiao Kui's wrongful death, she was so devastated that she no longer had the courage to go on living. She chose to die.
But when she was rescued and woke again, she had forgotten every trace of that love.
Five years later, the Xijue invaded the northern frontier once more, but Jiang Chengyue nearly wiped out their entire nation.
The northern frontier won a resounding victory, yet the events behind the battle proved shrouded in mystery and intrigue, even implicating the death of Prince Zhennan seven years earlier.
To uncover the truth, she stepped into the game herself, only to encounter Xiao Yunmo once more.
Xiao Yunmo: “A Yue, it's you I love, and only you.”
Jiang Chengyue: “...But I'm not into men.”
