The Maid I Hired Recently Is Mysterious Vol. 1 (manga)

There's something really strange about the maid I just hired! No normal person could be so beautiful, or cook such amazingly delicious food, or know exactly what I want before I even ask. She must be using magic--right, a spell is the only thing that can explain why my chest feels so tight whenever I look at her. I swear, I'm going to get to the bottom of what makes this maid so...mysterious!
