A low-ranking maid in the secluded residence of a prince's household unexpectedly forms a bond with the young heir. By a stroke of luck, she obtains a document granting her freedom, but an unborn child throws all her plans into disarray. She withdraws from the world and lives in seclusion, raising her child alone. Unexpectedly, she also rediscovers her rightful noble family identity. The once youthful and inexperienced heir overcomes countless political intrigues and obstacles to ascend the throne and rule an empire. Yet, deep in his heart, he has always kept a place for the woman who once wore a pale green dress. After years apart, they reunite. Defying the judgment of society, he brings her and their child into the imperial palace and bestows upon her the title of Empress, promising to remain by her side year after year.
