There was a little episode in the process of acquiring the rights to "Migration to Mars."

When Cosmic Entertainment bought the IP, Pluto was still an unknown author. No one was willing to buy the copyrights to his novels, even when the publisher bundled his novels together at a low price.

At that time, the person in charge of Cosmic Entertainment's film production department had a personal relationship with Pluto's editor, so they purchased the rights to this particular book out of goodwill.
