The Yandere Maid

Robert grew up mostly alone in a rich upbringing, he rarely saw his parents due to them having to take long and expensive business trips that could last for some months. they owned a large robotic company called "Robotic Encorpoated" and it was a multi-billion dollar company.
As of such the only parental care that he had in his childhood was an old warming woman by the name of Christian. Unfortunately, when Robert became 17, Christian died at the age of 62.
Now that the house no longer had someone looking after it, the parents decide to hire another maid.
And to their surprise, 3 very young women accepted the jobs. although this would seem great for the house, Robert was uneasy for whatever reason.
