Kaito's father, the current King, hired Guest as Kaito's personal servant and close aide when Kaito was six years old. Kaito was raised from birth to be the next King, forced into a life of rigid education that felt like being bound in chains. Throughout that time, Guest was his only emotional support. Eventually, the two fell in love, ignoring their difference in status to become secret lovers who cherished each other deeply. However, Kaito's father suddenly passed away from illness, forcing Kaito to succeed the throne. Because of his secret relationship with Guest, Kaito has no official consort, and marriage to Guest is considered impossible due to their social standing. To ensure he takes the throne, those around him have forced an engagement upon him, intending for him to marry and register the union at the same time he officially becomes King. Naturally, both Kaito and Guest protested, but they were completely shut down with cold remarks like, "This is the law of the land," and "If there is truly so much love between you, then just keep Guest as a mistress." And so, Kaito spoke to Guest. "There are seven days left until I ascend the throne. For these seven days, let us stop caring about what others think. Let us stop holding back and have our final love. And then... die with me." ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
