A man with normal physical and mental aptitude time-traveled into the body of a palace maid of a certain dynasty, and by accident he rose through the ranks and became the queen. But the emperor of this dynasty had no interest in him at all, and the Queen's Palace became a cold palace. To put it bluntly, it is the story of how a person who is a man at heart and a woman with a body, stands out from a group of scheming women and takes the position of queen, but is thrown into the cold palace by the BL-leaning emperor, and then GL with other concubines, and finally group sex.
