I Was Proposed to by an Unknown Duke After My Sister Stole My Fiancé

PROLOGUE

CHAPTER 1

 

Shall I tell you the story of a pitiful woman?

 

This woman had a fiancé.
He was a handsome man from a very prestigious family.
Although he was somewhat easily swayed, the woman liked that about him.

 

As he was the third son, both families agreed to their engagement with the promise that he would marry into the woman's family to support them.
They had been together for eight years since the woman was ten years old.

 

Yes, that means she dedicated the most enjoyable and beautiful time of her life to him.
Ha ha, do you know how important that time is for a young lady?

 

Well, never mind.
They were supposed to get married soon.

 

However, despite all this…

 

The man betrayed her terribly.

 

He slept with the woman's little sister.

 

Oh, that's not a word a lady would say, is it? Please ignore it as drunken nonsense.
Besides, it's the younger sister who is not acting like a lady.

 

…Ahem, let's get back to the story.

 

From a young age, the younger sister had always been jealous of the woman.
As a result, the woman had suffered countless times.
Just thinking about it…
Hmm, should we stop this story?

 

However, the woman had no idea that her sister had such hobby of stealing men.
And when she confronted her sister, what do you think she said?

 

“I've always wanted to take him away from you, big sister.”

 

“Well, then why now? Isn't that obvious?”

 

“Because it'll be even more satisfying to see your face in despair.”

 

It's insane, isn't it!

 

I really doubted if I was related to such a person.
Oh, this isn't my story, by the way.

 

But if that was all, the woman could still endure it.
The younger sister had no inheritance rights, and the man had no territory as the third son.
So, if they got married, they would become commoners and never appear in her sight again.

 

However, even so!

 

The man suggested they should get married as planned and proposed to marry her as if nothing had happened!

 

“I didn't mean any harm.
I just went out with her because Olivia insisted, but I really do love you.”

 

I felt like pushing him down the stairs.
Of course, this is just a story about an acquaintance.

 

The woman's parents supported the man's family, even though the woman wanted nothing to do with him and to ban him from ever coming back.
They thought that the family was more important than their daughter, apparently, and they feared that if their daughter didn't get married, their family would collapse.

 

Well, I can understand t
