[cmoa exclusive](https://www.cmoa.jp/title/354956/) Duke’s daughter Emily and Crown Prince Laios have been betrothed since childhood. In the Empire, marriages are determined by the "Ritual of the Divine Mirror," and only those who truly love one another receive its radiant blessing. Emily had eagerly awaited this day. However, upon returning from years of study abroad, Laios is cold—like a different person—and the Divine Mirror fails to shine during the ritual. Repeatedly rebuffed in her attempts to bridge the distance between them, a heartbroken Emily finally resolves to break off the engagement.
