Her thoughts

"Here, sign this oath, or I will kill you."

Seeing the oath suddenly thrown at her, Ivy was surprised.

Because, in her entire life, this was the first time such a thing happened in front of her.

She and her sister were war children from a city that was destroyed after the expansion of the Empire.

Because of that, their life was hard. 

With their stomach empty, with nobody to rely on.

Therefore, they were always together.

Because they did not have anybody to rely on.

Until the point when an orphanage accepted them.

And they have learned something from all those times they have lived.

In this world, the strong always ate the weak.

This was what they had learned.

And thanks to the blessings they got after they had applied to the church with the orphanage, they were on the stronger side of the world.

After some point, they got out of the orphanage and became an adult who could support themselves.
