Seraphina, who received a divine oracle in her youth and became a holy maiden. She was demanded to live in holy poverty and charity, and had everything—her treasures, her food, and even her betrothed—taken from her by her younger sister Mireille. And then, the first prince Lucian declared he had "found true love," broke his engagement with Seraphina, and announced his marriage to her sister instead. Now, Seraphina herself is being told to preside over the two's wedding ceremony "as a holy maiden" and bestow her blessings upon them. If that is what they demand, then so be it. If the two of them truly have the resolve for this. And so, the wedding ceremony began.
