He Passed the Imperial Exams, While I Was Plagued by Gu for Life

In the 1970s, amid a sea of rapeseed blossoms in the Miao Mountains, a promise of marriage binds two hearts and sparks a love in the depths of the mountains. When the winds of the college entrance exam sweep in, their original resolve falters before the lure of prosperity, and their engagement teeters on the brink of collapse. Will the elder brother, fiercely protective of his younger sister and master of the Miao frontier's Gu magic, cross that forbidden line for her? Will this love be ensnared by Gu poison, or redeemed by time?
