Caught Between Two Worlds

The childhood companion arrived from the future when I had already been a concubine in the Vanderbilt Mansion for three years.
Rumors spread that the Sovereign's personality had drastically changed since his near-drowning incident.
He began cleaning house with thunderous methods, causing rivers of blood to flow through the mansions of various officials.
It wasn't until the Lantern Festival that the King caught a glimpse of me. The very next day, he issued a decree to forcibly bring me into the palace and crown me as his queen.
The court officials were outraged. The usually aloof Lord Hale even knelt outside the palace gates until his forehead was bloodied from kowtowing.
But no one knew that inside the Capitol Rotunda, the ruthless King was sitting across from me, sharing a hot pot meal.
He held his wine glass, feigning nonchalance as he asked:
'If I were to fight with your husband in the future, would you side with me or with him?'
