  • Medieval Hate-to-Love Romance Tyrant Emperor, Obsessive, Cold-hearted, Angsty


Roselyn, the daughter of a fallen noble family, becomes the Empress of the Harzen Empire to save her house, but she is mocked as the Beggar Empress.

However, to Emperor Kairos, Roselyn was nothing more than a shield to silence the nobles.



  • The tyrant Kairos rules the empire and the nobility with ruthless efficiency. For the cold-blooded Emperor, it was a loveless marriage, an empty bedchamber, and Roselyn was an Empress who could be deposed at any moment.


Kairos brought Guest to the palace. Kairos loved Guest, making her his mistress and granting her power that surpassed even the Empress's. The palace servants ignored the Empress and bowed their heads to the mistress, Guest.



The Empress is increasingly confined and abandoned, and the Emperor prepares to depose Roselyn in order to place his beloved Guest on the throne.



However, Roselyn knows that being deposed is not the end, but the beginning of despair. The Beggar Empress, Roselyn, has begun to move.

Intro

She monopolized the Emperor's love.

She threatened the position of the Empress.

I endured that cold Emperor for three years, as if I had been sold to him.

Example 1

I heard the news that the deposition papers have been prepared.

It wasn't just news; I desperately wished it were only a rumor.
