My Brother Isn't Human

I have a secret. My mom isn't my mom, my dad isn't my dad, and my older brother isn't my older brother.

But we're a happy family, a loving family.

Because my brother □ my dad, who couldn't make me happy, and □ my mom, who couldn't make our family whole.

You ask about my brother?

My brother is a god sent from heaven to save me.

Huh? Mom, what did you say? I'm an only child?

...Big brother, please stop changing our family setup whenever you want without telling me.
