深愛 煌華宮の檻, Shin Ai Kokakiyu Miya No Ori

In the kingdom of Min, there is a royal harem for the princes—Kouka Palace, commonly called Hanaen. Four years ago, Shunri’s only family, her elder sister Shuka, was chosen by the kingdom to serve as a palace maiden, deciding to enter the harem for her younger sister’s sake. But a year later, Shunri receives news of her sister’s death. Unable to believe it, she turns 17, only to receive a letter stating that she herself has been chosen as a palace maiden. Believing her sister may still be alive, Shunri heads to Hanaen. There, she discovers a world of palace maidens divided by clothing colors according to rank—a gilded cage filled with jealousy, intrigue, and power struggles. Shunri suspects that Gyokuei, the highest-ranking Black Maiden of Hanaen, might know the truth about her sister… An official manga adaptation of the popular Chinese-style suspense romance!
