Exists, but does not exist

prolog

My younger brother died.

It is said that he took his own life because he could not endure his unstable mental state.

Why would such a bright child...

And I am not me from now on.

아버지

Kang Yeo-ju,

강여주

yes

아버지

As of today, you are your younger sibling.

강여주

What? What do you mean...

아버지

As you know, people know about your younger sister, Yeoeun.

아버지

In contrast, you... since you are the undisclosed daughter, you must become Kang Yeo-eun.

You might think this is complete nonsense, but...

The father is a figure of high national authority, and since his approval rating could drop if his daughter causes even a minor incident, she must manage her daughter carefully.

However, in my case-...

I was bullied when I was young, and now I'm even retaking my college entrance exams...

My father has no intention of revealing me as his daughter.

He simply revealed only my younger sister, Kang Yeo-eun, who is doing well at school and is very good at studying, as his daughter.

아버지

You know very well that my approval rating will definitely drop if it becomes known that Yeoeun committed suicide due to an unstable psychological state, right?

강여주

... yes

아버지

Since you don't exist to the people anyway, you have to replace Kang Yeo-eun.

아버지

Oh, and don't worry about the name, Yeoeun, you can just say she changed her name to Yeoju.

아버지

Don't live your life so pathetically like usual; you have to act like you've really become Kang Yeo-eun.

아버지

So that no one... would suspect.

강여주

...

I hated my father so much.

So, from now on, I...

It is an existence that exists, yet does not exist.
