Such a criminally underrated manga. Each of the four main princes, as well as their relationships to Heine, to one another, and to others around them is developed perfectly. They're adorable and loveable from the very beginning but get even better and become fit for the throne as time goes on. The art is really beautiful, it looks amazing whether the scene is detailed and beautiful or simple and cute or funny and exaggerated. There's a perfect mix of the main plot and cute little side stories that are between one and a couple chapters long. The official art is beautiful, too. The covers andcoloured pages are absolutely stunning. A great manga if you want something mostly fun and cute but with a bit of darkness/sadness in the backstories and character development. One of my favourite manga of all time.
