When my appendix bursts, my parents, my brother, and even my fiancé are all too busy celebrating my sister's birthday. I'm outside the operating room, frantically calling every family member I can think of to sign the consent form, but every call is either ignored or hung up on. After hanging up on me, my fiancé, Joel Graham, texts back. "Sophie, stop being dramatic. It's Yvette's 18th birthday today. Whatever it is can wait until after the party." I quietly set my phone down and sign the consent form myself. It's the ninety-ninth time they've chosen Yvette Norton, my sister, over me. This time, I choose not to care. I'll stop letting their favoritism hurt me. Instead, I'll do everything they ask of me without complaint. They'll all think I've finally learned to be obedient, and they'll never realize that I'm preparing to leave them for good.

At the contract ceremony, Finn Carter is mocked for summoning only an F-rank white fox, leaving him on the brink of slavery. Just then, he awakens the Divine Evolution System, which reveals the fox's hidden demon bloodline and triggers a celestial phenomenon. Granted a probationary chance, Finn is sent to a mining camp—where completing the system’s task allows the fox to evolve and returns power to him.
