I know that my future self just told my sister about this.

But my sister still firmly told me that the shackles can only be unlocked once.

Because she loves me too, she doesn't want me to lose thousands of years of freedom to save them.

But sister, if all of you are gone, this freedom will become the shackles that imprison me.

I won't be happy for the rest of my life.

"I want to know, who am I?"

After I asked this question, not another word appeared in the notebook.

Just when I thought she wouldn't answer, a bright light suddenly appeared in my room.

A woman who looked exactly like me appeared in front of me.

But her eyes were filled with sadness, as if she had experienced long and lonely years.

Seeing this, I knew what she had been through.

The things in the dream were her past experiences.

She reached out her hand, and I held it.

A fragment of her memory appeared in my mind.
