While the plot is driven by mystery, the heart of the series has always been the relationship between its two protagonists. Volume 9 puts this bond to the ultimate test.

★★★★★ (5/5) – Heartbreaking, beautiful, and necessary.

At the heart of Volume 9 is the confrontation with Richard’s past and the toxic legacy of the de Vulpian family. For the majority of the series, Richard is portrayed as an ethereal, nearly flawless figure—brilliant, beautiful, and possessing an almost supernatural composure. However, this volume systematically strips away that armor. The narrative forces Richard to confront the manipulation of his family, particularly regarding the inheritance dispute that has haunted his background. Here, the jewelry ceases to be merely a plot device or a metaphor for a client's hidden feelings; instead, it becomes a physical manifestation of Richard’s own trapped reality. The gems represent the high-society expectations and cold, transactional relationships that defined his youth.

Volume 9 is highly regarded by fans for its focus on the deepening bond between the protagonists.
