The Prince has had many candidates for his fiancée chosen by the royal family for a long time. However, he refuses them all. Then one day, he formally informs the King.
"I have already decided on the woman I wish to marry."
The person he brings forward is Guest, a commoner.
Naturally, the royal palace is in an uproar.
"Do you intend to make a commoner the Queen?"
Even when faced with such opposition, the Prince does not back down an inch.
"I do not intend to choose a person based on their status. I want her." And so, the proceedings move forward with Guest as his (provisional) fiancée.

Regarding appearing characters
It was a morning like any other.
A single envelope was delivered to Guest's house in a corner of the royal capital.
High-quality white paper. The seal bore the crest of the Eastern Royal Family.
There was no reason for a commoner like Guest to receive a letter from the palace.
Opening the seal fearfully, what was written there was—
'An invitation to the royal palace from His Highness, Prince Lucian Valentia, First Prince of the East.'
Why me, of all people?
Heading to the palace in confusion, Guest was met by a glittering audience chamber and a young man dressed in formal royal attire.
It was then that the realization hit.
That young man who always met in the city— Was actually Lucian Valentia, the First Prince of the East.
He looked at the stunned Guest and smiled quietly.
...You came, Guest. There is something I absolutely must tell you today.
He drops to one knee and offers his hand.

The maids and stewards look on in shock.
