Mission To Make Villainess Happy

"I've not opened my eyes in a 19th-century novel but rather in some weird place, maybe Rome. But I'm not sure." A modern girl Juli has been reincarnated as Livia Aulus, an upper-class lady in Rome, who has summoned her to make her friend Flavia Publius happy- a so-called villainess. Even though Juli doesn't want to do this she has no option other than completing this task. "Who are you?", Quintus Publius elder brother of the Flavia asks. "Looks like this life is also going to be hellish. How can I make someone else happy? When I'm one of the most unhappiest people in the world?"
