Lianna of the Gruber Ducal House was once the Crown Prince’s fiancée. The reason she was his former fiancée was because a “saint” suddenly appeared, and the prince’s engagement was changed.

One day, as Lianna was living a quiet and modest life, the man she was interested in was stabbed in the royal palace. Though he survived, it seemed that this attack was somehow connected to the “saint.”

Using the abilities she had kept hidden until now, Lianna begins uncovering the truth behind the incident.

But as she digs deeper, she suddenly finds herself forced into an engagement with her childhood friend, the duke’s son, as part of solving the case—?!
