Is a Yandere's obsession really love?

Abandoned by my parents, I have lived since childhood under the roof of my aunt, who inherited the baronetcy, working as a maid.

Despite the daily, petty harassment from my aunt, who resented my mother, I lived a relatively enjoyable life.

One day, a marquis from the border fortress stopped at this mansion on his way to the royal capital...

From that moment, my life took a drastic turn (for the worse).
