I had loved “him” unrequitedly for a very long time.

However,

to him, Hayeon wasn’t a woman.
If you put it nicely, she was a junior from the same club.
And if you went a little further, she was a girl from the same workplace. That was it.

But he’s getting married?

“I’m going to go on a blind date and get married as quickly as possible.”

Hayeon could not contain the emotions she had held on to for a long time when he said he would do a contract marriage with a woman he didn’t know.

I died miserably, on the day I found out the truth. The truth, that my fiance had a hidden lover and it was my very own cousin.

On the second morning, after my 20th birthday, a miracle happened. From that point on, I decided not to believe in love anymore.

I want to have a relationship with no strings attached and without any superficial feelings such as love.

"Duchess Agenstein, will you marry me?"

“...There’s something I’ve been thinking about doing. I won’t be able to use the money anyway.”
Clea always lied. This body will soon die. It’ll barely last half a year.

"A bargain for 5 billion marukas."
"Sure enough, it's a bargain."
