The Villainess’s Personal Maid Is Very Good At Her Job

Janet is a war orphan who was adopted into the Graham family.
One day, with about half a year left before her coming-of-age birthday:
“This is the man who will become your husband.”
She finds out that her adoptive father plans to send her away to become the fifth wife of an old count.
There is only one way to escape the Graham family’s grasp and find freedom: becoming the maid of Julietta Ludwig, the empire’s notorious villainess.
‘Because maids of unmarried young ladies are strictly forbidden from getting engaged or married while working.’
But then…
“You don’t need to stay silent about unfair things. Revenge whatever you want to revenge.”
“I will become your backer.”
The vice-commander of the information guild, whom she went to see for help, promises to support her.
“Janet, I am your number one friend, right?”
And somehow, she even completely opens the heart of the villainess.
