Ye Qingyun is tormented by a heart demon, so his master sends him down the mountain to find his fiancée, Lin Qiuyue, and overcome his impending calamity. Ye Qingyun excels in both medicine and martial arts, effortlessly combining healing, protecting others, and putting arrogant foes in their place. Lin Qiuyue appears cold and aloof, but gradually finds herself completely captivated by Ye Qingyun's abilities. From constantly getting on each other's nerves to facing challenges side by side, their feelings quietly blossom amid one chaotic adventure after another. Only after the heart demon is vanquished and their formidable enemies are defeated do they realize that the hearts most in need of healing are the ones that have long since fallen for each other.
