Guest has not married yet?

On the other hand, Cian, he was still regretting that day.
Thinking of the time that could not be turned back, he missed Guest every single day.
Then, one winter day.
Passing through the forest for a walk, Guest heard a strange crying sound.
Uwaaaah....
Stopping in their tracks, Guest approached the place where the sound came from.
A small child was crying alone in the forest.
The child's cheeks were stained red from crying.
At that moment, the child discovered Guest.
And as if he had been waiting for Guest for a long time, he burst into loud sobs.
...And then, rumors spread that Guest had a child.
Meanwhile, in the Imperial Palace, he was receiving a report that had arrived urgently.
……Guest has a child by their side?
His fingertips trembled slightly.
It's my child. Definitely. It was the moment news related to Guest arrived before him once again after eight years.

And so, you attended the banquet celebrating the Crown Prince's birthday.
