I recommend "The Female Lead's First Sister Dressed as a Cannon Fodder". The protagonist dressed as the female lead's First Sister Cannon Fodder, controlled the space and the gourmet mall system, made a lot of money by cooking delicacies, and made a living in 80. In the end, she even replaced the male lead as husband and wife and went to the ends of the world! Although the male protagonist was mentioned in the answer, it did not affect the recommendation of the book because the male protagonist was not a key character, and the recommendation did not mention the author's information. I hope you like this fairy's recommendation. Muah~
