I really liked the character of this charitable, gentle, intelligent and fair prince. Everything he did was for the good of the king and family at the cost of sacrificing his own life .
The character of the doctor's daughter was also great. A strong woman with healthy principles who wants to make up for her father's mistakes.
The flaw of this series... I don't know if many poisons were used frequently in this era but in this series there were daily poisonings and many people, too many, spitting blood from their mouths when they died.
While I particularly appreciated the ending that made me finish with a smile.
Here too the prince carried out his duty as sovereign well, after which he dropped everything and thought about his own happiness. First duty, then pleasure. Good teaching.
