Also known as: How Could a Young Lady's Maid Ever Overstep Her Bounds?
A young master admired by all turns into a girl after drinking a strange beverage.
To help her adjust to her new identity as a young lady, her father actually assigns her a personal maid to look after her.
But her maid gradually starts acting a little strange.
"Young lady, let me wash your undergarments."
"Young lady, I'll wash you today. It'll help you adjust to being a girl faster."
"Young lady, don't trust anyone who tries to get close to you. I'll always be by your side."
The young lady feels uneasy as her maid becomes increasingly yandere.
At last, one day, the maid can't hold back any longer and pins the young lady against a corner.
"Young lady, you wouldn't want those people to fail to see tomorrow's sunrise because of you, would you?"
"Be a good girl and do as I say, okay?"
