On the very first day after moving into our new home, my next-door neighbor confronted me with an agreement and demanded that I sell her the apartment at 80% of its market value. When I refused, she repeatedly rang my doorbell late at night, claiming she had forgotten her access card and frightening my young daughter to tears. The property management urged me to be accommodating, while the neighbor insisted that I should take a step back. It wasn't until I discovered that she hadn't actually forgotten her card, but was deliberately trying to pressure me into selling at a bargain price, that I began collecting evidence to expose her true intentions to everyone. What started as a neighborhood dispute gradually revealed a much more calculated scheme.
