Song Ming has a wish.
He hopes to have a little sister.
Illyasviel, Asuna, and other familiar anime girls suddenly appear before him.
What? You want me to join the Service Club? Hachiman, didn't your story already end?
What? You want me to play a death game? Hey, you look familiar. Are you Kirito?
What? Life counseling?
What, what? You want me to write a novel? Sure! I'll write one for you!
And so, in a different world, a boy named Song Ming begins his new life, together with his little sisters?
(Note: Secret little-sister romance story, heroine is Illyasviel, original couples stay together, author has normal values.)
