Be prepared to fall in love with the characters, their development is so well handled and their acting is on point.
Everything in this drama screams acting masterclass.

I was pulled into their court intrigues and felt deeply about our main couple who are world weary and have been betrayed by the very people they admire and have vowed to protect. Their relationship is a constant, the chemistry and respect is palpable.
Ruyi is one of the strongest female leads I have encountered. She is proud, fierce incredibly talented, flirtatious, outrageous and admirable.

The young naive princess Yang Ying is a hidden gem. Her emergence from terrified female out of her depth in dangerous situations to a person who weighs up the difficulties and makes informed choices is terrific to watch.
There are lots of bad/evil characters but one of the most interesting is Ruyi's disciple, Li Tongguang, his plotting and machinations make him an easy fall guy target and his obsessive stalker behaviour to his shifu creates lots of opportunities for conflict.

If you come on this journey and hold out to climactic last episodes you will probably need several boxes of tissues. For me the most heart rending is watching the youngest member of the delegation. Yuan Lu, who despite his heart issues pushes his body to exhaustion delivering the vitally important message requesting military back up for his brother. Then there is Shisan, known as a playboy and lover of all things beautiful in life, making sure the woman he loves is safe before making a final heroic stand fending off the enemies.
