The heroine Chen Yuli was born as a concubine, grew up in the shadow of her family, and never gained her father's favor and status. By chance, she was brought into the palace by Xiao Sheng, the most powerful prince, as his dowry. At first, Chen Yuli regarded this marriage as a political marriage, and she kept a low profile in front of the prince's ruthlessness. However, as time went by, she discovered that Xiao Sheng was not as cold-blooded and ruthless as the outside world rumored, but a man with a deep scheming mind and a lonely soul. Relying on her intelligence and tenacity, Chen Yuli not only gained a firm foothold in the prince's harem, but also used her own wisdom to help Xiao Sheng resolve many palace conspiracies, gradually winning his respect and love. From the initial misunderstanding of each other, the two gradually established deep trust and emotions, and finally worked together to overcome difficulties in the game of intrigue and love. Chen Yuli also became a real princess through her own efforts, achieving a counterattack from a concubine to the center of power.
