He is a history graduate student with a strong sense of justice. By a twist of fate, he returns to the Warring States era a thousand years in the past, where he will spend his life pursuing the ideal he could not fulfill in his previous life. He is an emperor in one life, someone who crossed paths with him in a past life, only for the cruelty of fate to keep them apart. He is the emperor's male favorite, defying every taboo and harboring a secret, all so he can be with the one he loves. He is Kaiyang, one of the Six Envoys, free-spirited and unruly, audacious and brilliant, yet destined to be alone all his life. Faced with the choice between loving and losing, he chooses loss... Before the throne, before the eyes of the world, before taboos and fate, countless entanglements and romances will be reborn amid the light of the Big Dipper, across a thousand years... How can a few sheets of blank paper tell the rise and fall of the tide?
