In return, I will ask you to marry me!

Leonard Elpiers. Having come to the capital to earn money to pay off his debts, he receives a small favor from a woman he meets for the very first time.

“Thank you for your help. Is there anything I can do for you in return?”

“Of course, there are plenty of things.”

She asks for an escort as her repayment, and Leonard accepts.

He had no inkling whatsoever. That the repayment she desired wouldn’t end with just an escort.

“This man right here is the one I’ve promised to marry!”

Nor that he would be bound to her for the rest of his life.

Irenea Blair. After suddenly losing her parents, she had everything they left behind—her title, territory, wealth, and even her very life—stolen away by her uncle.

And then, she returned. To a time before everything was taken from her.

“This time, I will not lose a single thing. Not my life, not my parents’ inheritance, and not the future of my younger siblings.”

And there was one more thing. Something she absolutely had to reclaim.

“Please marry me, Sir Leonard.”

“It seems you are quite unaware, but I am the son of a mistress.”

“How is that your fault? Not a single person in this world can choose their parents.”

“……Do you truly not consider that fact a flaw of mine?”

“Of course not. If you marry me, I’ll make sure you never think that way again.”

My merciless knight, whose very first and final broken promise was, of all things, the vow never to die before me.

“Not just Sir Leonard, but everyone who made Sir Leonard think that way… every single one of them.”
This time, I will protect you.
