The Villainous Bigwigs' Parenting App

[The next novel is a no-romance child-rearing story. If you're interested, please add it to your collection! The protagonist is a little one inside an app, with lots of powerful villain dads and moms. It's a healing story with no romance.]

Overnight, powerful villains in various worlds all received a smartphone. There was a world of infinite realms, a world of interstellar civilization, a world of Western fantasy, and more...

There was only one app on the phone.

Inside the app was an unknown little cub, about to hatch.

A phone System notification appeared: Please work hard to raise the little cub's affection for you and bring them up well. Otherwise, you will die.

At first, the powerful villains were all dissatisfied, and some even considered taking the System down with them.

Gradually, the little cubs melted their hearts and healed them after hatching, and the villains enthusiastically took up careers as professional dads and moms.

I'll flesh out the blurb later, little by little TvT. That's basically the story, and it won't change.
