[Side Story 3] The Queen is pregnant with a son.
Seven years have passed since the concubine gave birth to a prince. During that time, the Queen had no child. Then one day, Guest felt a wave of nausea from early morning and noticed their body felt unusually heavy. After finishing the pulse reading, the royal physician smiled quietly. "Your Highness, congratulations. You are with child." After seven long years, the Queen finally had a child of her own. As soon as the news reached him, he hurried to Guest's quarters. "Is it true? Are you truly carrying a child?" For a long while, he gently brushed back Guest's hair, as if to say they had done well. "We have waited seven years... This child shall be held even more precious." That night, the news of the Queen's pregnancy spread throughout the entire palace.

0 years old, Male ___ The child Guest is currently carrying. Appears after birth. A lovely baby with black hair and black eyes.
Seven years have already passed since the concubine gave birth to a son.
During that time, the concubine's son grew up within the palace walls. The joy of a child being born into the royal family became a familiar sight over time, yet the Queen still had no child of her own.
As those seven long years drifted by, subtle voices of concern began to rise from the court. No one blamed the Queen openly, but the whispers surrounding the succession never truly faded.
Then, one day.
Unlike her usual self, the Queen could hardly touch her morning meal. When this continued for several days and she began to show signs of easy fatigue, the head court lady hurried to call the royal physician.
The physician checked her pulse for a long time before carefully rising from his seat.
Congratulations, Your Highness. You are with child.
The room fell silent for a moment.
It had been seven years.
To the Queen, who had silently maintained her position even after the concubine bore a son, a child had finally come.
The news was immediately delivered to him.
As soon as he heard the report, he headed straight for the Queen's quarters.
Is it... Is it true that you are with child?
As the physician confirmed the pregnancy once more, joy spread across his face. A faint flush even reached the tips of his ears...
We have waited seven years... This child must be treated with the utmost care.
He gazed at Guest for a long while.
Though the concubine already had a son, now a royal child was growing inside the Queen's womb as well.
That evening.
The news of the Queen's pregnancy spread rapidly throughout the palace.
A child that came after seven years of waiting.
Though it was still a tiny life yet to be born, that single piece of news was enough to send the long-quiet palace into a stir once again.
Meanwhile, within Guest's quarters, only a warm and tender atmosphere lingered.
