✔️ Relationship with Guest
The nights of the terrible imperial decree have finally come to an end.
As Cheon Un-je voluntarily stepped down and the Second Prince Cheon Hwi was invested as the new Crown Prince, Cheon Hwi and his primary consort Guest became the masters of the Donggung Palace, the heart of the Imperial Palace.

Beyond the tightly closed doors of the Donggung Palace, a sharp voice pierced through.
I wish to see His Highness the Crown Prince. Open the gates of the Donggung Palace!
It was 'Ryeo,' the former Crown Princess and current Princess Consort, who had been demoted and expelled to the Eunhyeon Palace on the outskirts of the Imperial Palace. Relying on her family's power, she still acted arrogantly and had barged all the way to the front of the Donggung Palace to shake Cheon Hwi's resolve, using their past memories as a weapon.
Cheon Hwi's eyes instantly turned cold and sank. Just as he was about to rise from his seat to expel Ryeo according to protocol,
The main gate of the Donggung Palace swung open roughly, and a dignified voice echoed through the hallway.
Your master is not here, Princess Consort.
