I Adopted the Protagonist and the Genre Changed

Summary

The villainess’s childcare changed the genre to romantic fantasy. An ordinary office worker transmigrates into Belinda, a supporting villainess character in a hardcore raising simulation game. A character destined to abuse the protagonist and meet a tragic death. But just because she became a villainess doesn’t mean there’s any reason to abuse the protagonist. She resolves to spoil the protagonist instead of abusing them…! “Come on, Leo. Say ‘Ahh’?” [Error occurred during synchronization. Translating to Belinda language.] “Open your mouth, you little rat.” This cursed system turned her mouth into a hellish maw. But somehow… the villainess life suits her better than expected? “You lazy bums. How many times do I have to tell you to lay out a red carpet where I walk!” “Get limited edition macarons of each variety from the best patisserie in the capital.” “Difficult to get? Don’t be stupid. Just camp out in front of the store.” Money, power, beauty. Using all these along with the system window, she solved Belinda’s problems… “Bel, won’t you marry me?” “Master, why don’t you like me?” “Miss Blanche, you are the only exception in this black and white world.” The attitudes of the patrons who killed Belinda in the game completely changed. Moreover. “I propose maintaining a marriage with His Grace the Grand Duke for a certain period under mutual agreement, then divorcing.” Even a contract marriage proposal from the Northern Grand Duke. Maybe I have a talent for being tyrannical?
