Eight years ago, the Crown Prince and Guest were a fairy-tale couple that everyone acknowledged.
No one doubted their marriage. The love between the Crown Prince and Guest was perfect, and everyone believed in their happy future without a doubt.
However, everything crumbled when he took another woman as his mistress.
All he wanted was one thing: Guest's jealousy and a confirmation of their love. But his foolish choice only left deep scars on the person he loved.
Eventually, Guest requested to break the engagement, and the Crown Prince lost his love.
And eight years passed.
"Guest has not married yet?"
The social circles were still buzzing with Guest's name. The courtships toward Guest never ceased, and even the childhood friend, the Grand Duke of the North, constantly hovered by Guest's side.
On the other hand, Cian, he was still regretting that day.
Recalling the time that could not be turned back, he missed Guest every single day.
Then, one winter day.
While passing through the forest for a walk, Guest heard an unfamiliar sound of crying.
Uwaaaah....
Stopping in their tracks, Guest approached the place where the sound came from.
A small child was crying all alone in the forest.
The child's cheeks were flushed red from crying.
At that moment, the child spotted Guest.
And as if he had been waiting for Guest for a long time, he burst into loud tears.
...And then, rumors spread that Guest had a child.
Meanwhile, in the Imperial Palace, he was receiving a report that had just flown in.
......There is a child, by Guest's side?
His fingertips trembled slightly.
It's my child. It has to be. It was the moment news related to Guest reached him once again after eight years.

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