The Male Harem's Evil God Cultivation Plan

A high fever sent Emma into a cosmic-horror fantasy novel she'd happened to finish reading, where she somehow became the mistress of a minor male character who'd been killed off in a few hasty lines.

Looking at this cannon-fodder minor character with an unbeatable character design and a broken brain, Emma, a helpless nobody in a chaotic world with no one to rely on, resolved to keep him from dying a widower by raising him into a fake cannon fodder and a real evil god.

Before the romance:

"Hello, I'm Emma, your mistress."

"You're nothing but a shameless bar hostess, a filthy lowborn. Stay away from me."

After the romance:

"Emma Morn, if you keep flirting with other people, I'll transform into an evil god and show you!"

The minor male character held a knife to his own neck, eyes brimming with tears (absolutely certain).

P.S.

I'm planning to write a sweet romance about saving each other. 1v1. Both the female and male leads are gloomy little demons from hell.

Theme: Persevere through hardship, work diligently, and never give up.
