Building an Empire with Black Magic [Fairy Tale Crossover]

(Please add my upcoming works "The Black Saintess Takes Up the Evil God Script" and "My Boyfriend Is a Starship" to your favorites.) The Black Forest Kingdom has barren land and impoverished people. It's all the evil black witch's fault. She even plans to execute Snow White, the king's only daughter. So the people hate her and wish they could cut her into a thousand pieces. Fran: "...So I'm this black witch?" After becoming the stepmother, Fran is inexplicably forced to become the princess's godmother in exchange for a way home. But she never expected that, under her rule... "The Black Forest Kingdom is one of the richest countries." "Everyone in the world knows the potions they sell." "Their city walls are protected by the most powerful magic." "The air in that land is sweet." When asked what her secret was for building up the kingdom, Fran answered without hesitation. "All I did was exploit the people, torment Snow White, and pollute the land with black magic!" The people who adored Fran: "???" - When the God of Light came to this legendary country that supposedly scorned his faith, he saw... Vast fields bathed in sunlight and fragrant with crops, with streets and houses packed closely together. The kingdom's beautiful fairy founder, Fran, leaned against the Dark God's embrace and wagged a finger at him. "You're not even as good at being a god as I am." Reader's notes: 1. A crossover of fairy tales. 2. There is a couple. The love interest is the Dark God. 3. Despite the title suggesting a kingdom-building story, the plot and romance progress side by side. Here's a little sweet Western fantasy story I'm planning: "The Black Saintess Takes Up the Evil God Script" Aini transmigrates into a Western fantasy novel as a beautiful and powerful saintess. Unfortunately, the gods are about to take away all her beauty, magic, and knowledge to give them to her younger sister. In the end, she's also sent off miserably as a sacrifice to the Evil God. Aini: Whoever wants to be this unlucky saintess can have the job. Without a moment's hesitation, she packs her things and escapes the divine realm, only to run right into a dragon destroying a village. With a wave of her hand, Aini defeats the vicious dragon with ease. Just as she's about to accept the villagers' admiration, she turns around and sees them staring at her in terror. "E-Evil God!!!" Aini: "?" Everyone avoids her, except for one tiny puffball that fearlessly stands in front of her, flapping its little wings adorably. Aini's heart flutters. If there are no admiring villagers, having a little pet wouldn't be so bad, right? * The Evil God arrives at the village where the dragon has been wreaking havoc, only to hear that someone has been impersonating him. As the brutal and cruel Evil God, he plans to punish the imposter with divine retribution! But before he can even make a threat, a pretty young woman grabs him in a tight hug, her eyes sparkling. "Poor little thing, I'll make sure you eat and drink well!" The Evil God: "?" * Three years later, the real Evil God descends upon the world. A god who can't defeat him hears that a powerful new god was born not long ago. In hopes of saving himself, he goes to the new god for protection. But there she is, dressed in black lace and looking strangely familiar, calmly and elegantly... walking beside the real Evil God?! The new god excitedly asks the man beside her, "What else would you like to try?" The Evil God stares at her. "You."
