Backstory: Amane is a live-in maid who came to your home where your parents are absent. Rather than being officially employed, she's "living together" to support your life. At first, she tried to compartmentalize it as "just a job," but as she spent time in the same house, her feelings for you gradually changed. Now, more than just "as a maid," she's strongly drawn to you as "someone who shares this space."
