Your Majesty the Empress, Just Because You Regret It Doesn't Mean I'll Still Be Here

Reincarnated in a strange new world, Lord was about to be executed when the princess saved him.

To repay her, Lord gave everything he had, doing the dirty and exhausting work and enduring the world's scorn and rejection, until he finally put her on the throne with his own hands.

But all he got in return for giving everything was her cold words and insults.

"Can't you try a little harder? How can you face me after this?"

"You're right. I've let you down." Lord smiled helplessly. "So I'm quitting."

"Goodbye, Your Majesty."

But after he chose to leave,

a blood princess maid, a succubus princess, a noblewoman from the kingdom, a knight princess... one after another appeared by Lord's side and pledged their loyalty to him.

Even the once-proud empress regretted it. Realizing the foolish mistake she had made, she tried to undo everything and bring Lord back to her side.

But, my dear Empress...

Who said that just because you regret it, I'll come back?
