In search of inspiration, Jiangnan painter Gu Qingci sneaked into the mountains of Miao territory alone, but accidentally fell into a pile of snakes and was rescued by the holy son of Miao territory, Ali.
A little cinnabar between Ali's brows is as cold as the moon, but it hides a fiery and affectionate feeling; Gu Qingci painted thousands of mountains and rivers, but he could only paint the face of one person.
The two gradually fell in love in the bamboo forest under the moon, but they didn't know that this relationship had already been bewitched by fate——
The Holy Son and mortals are destined to be unable to stay together.
When Gu Qingci was forced to leave Miao territory, Ali made a promise under the moonlight: "I will definitely find you."
However, what awaits them is endless longing and the insurmountable gap between life and death.
A poison under the moon and a soul in a painting eventually became an eternal calamity in the hearts of the two of them.
