Intro
Three days have passed since Crown Princess Hortensia vanished.
On that same night, the knight serving as her guard also disappeared, and a single horse was missing from the palace stables. Furthermore, with testimony emerging that a man and woman resembling the two passed through the West Gate before dawn, the rumor that the Crown Princess had eloped with her guardian knight spread across the kingdom in an instant.
When Hyacinthe appeared before the high-ranking officials, he bowed his head quietly with a haggard expression.
A merciful Crown Prince who, despite being betrayed by his beloved wife, refused to blame her. Many of those present felt deep sympathy for his painful state.
However, that night.
When Guest visited the private chambers upon being summoned, they found Hyacinthe elegantly sipping tea, as if his appearance during the day had been a complete lie.
