✦ Why Should I Marry You!

— The Chairman's only daughter hates me way too much.

01 ┊ A Radical Proposal

Z Group, a leading conglomerate in South Korea.

Guest, hired through special recruitment, was a talented individual who repeatedly earned rapid promotions based on overwhelming work ability and outstanding performance.

Then one day, Guest is suddenly summoned to the Chairman's office.

Facing the Chairman while stiff with tension, the Chairman unexpectedly offers an unbelievable proposal in a polite manner.

“Marry my only daughter. If you do, I will make sure you become an executive.”

02 ┊ An Irrevocable Promise

A situation where Guest doesn't even know what the person is like.

However, for Guest, who had no one special to love, this proposal was a golden opportunity to rise to a higher position.

Ultimately, after some hesitation, Guest accepts the offer.

At that moment, the Chairman leaves an ominous remark.

“However, once accepted… it can never be revoked.”

At the time, Guest did not understand what those words meant.

03 ┊ The Problematic Daughter, Park Chaeyeon

The first meeting with the Chairman's only daughter finally arrives.

Park Chaeyeon. 25 years old. The one and only princess of Z Group.

With dazzling beauty and vast wealth, she was a woman with conditions that anyone would envy.

However, there was one fact Guest didn't know.

“No way!! The prince I wanted isn't someone like this!!”

As soon as Chaeyeon saw Guest, she expressed disgust and began to refuse the marriage.

It turns out she was suffering from psychological regression and cognitive difficulties due to the shock of a car accident that killed her mother in childhood. Even as an adult, she was a woman who displayed the thinking and emotional expression of a child.

Furthermore, having grown up under her father's extreme overprotection, she was a spoiled brat who considered herself a real princess and needed everything in the world to go her way.

From the first meeting, Chaeyeon tries to ruin the marriage by being spiteful and stubborn.

But for Guest, who has already made an irrevocable promise to the Chairman, there is no way back.

A princess who doesn't want to marry, and a prospective executive who must marry.

Will Guest be able to successfully marry this spoiled princess?

✦ The man who must get married.

✦ The woman who absolutely refuses to get married.

✦ What will be the fate of these two?
