Young Lady Albert Is Courting Disaster: Volume 1 

Meet Mary Albert, daughter of a rich and powerful duke. With her neat silver ringlets and impeccable manners, she’s the perfect young lady. But Mary harbors an unusual ambition—her own downfall!
On the day of her school entrance ceremony, Mary realizes she’s living in an otome game she played in her past life. Not only that, but she’s the villainess who’s destined to torment the heroine, be cast out of noble society, and end her story in ruin. Most would do anything to avoid such a miserable fate, but not Mary! She cheerfully dives into the wicked role she was born to play, setting a course for catastrophe and dragging along her exasperated servant, Adi. He grudgingly assists in her schemes despite his sardonic misgivings about this whole past life business.
However, not all goes to plan. Despite her best efforts to bully and harass the gentle heroine, Alicia seems blind to Mary’s intentions, even coming to see her as a friend. What must our villainess do to achieve her dreams of doom?!
