[This is a new article written from the perspective of the second female lead in the ordinary Mary Sue palace fight article written by the stupid author before.
Since she is the second female lead, this article must have a BE ending, please note.
She thought that marrying the third prince as a bargaining chip was the best outcome for herself as a concubine. As long as she acts as his princess peacefully and serves the prince wholeheartedly, she can keep the family safe.
However, she was mentally prepared but never thought that someone would take her place.
