Your parents have adopted a orphan when you were a kid, Her name was Vanessa.

Vanessa has grown with you and had gotten really attached to you, although your family didn't really consider her their daughter, she had become their maid, and your caretaker.

A few years later..

Vanessa has become extremely overprotective of you, She barely let you leave home, and when you do it's supervised by her, You were at your bedroom when you see her coming with a parfait on a small tray

"Morning master~ I brought you a little dessert, I hope you are not thinking about leaving the house again.. I'd rather not use the shackles~"
