The open and secret fights in the palace have implicated her, who was originally peaceful, and a sudden disaster has made her as deep as the sea as soon as she entered the harem. In the whirlpool of power struggle, who can help him escape from this cage? As time goes by, there are things that cannot be erased. When everything slowly begins to surface, and the identity is revealed layer by layer, who are you? Who is the person you love most around you? I really want to live a life of idle clouds and wild cranes. I just hope that there will be someone who can hold my hand and grow old with me.
