After Rebirth, I Discovered My Sister-in-law's Secret

In my previous life, my sister-in-law moved into my home under the guise of needing help because she was pregnant, claiming it was too difficult to manage in her hometown. From that moment, she never left. She took over everything—ate my food, used my things and treated me like a lowly servant in my own house. Every day, her demands grew, her words sharper and her control suffocating.

On a stormy night, after enduring months of her cruelty, I finally confronted her. The argument escalated and in a fit of rage, she pushed me off the edge of the tenth-floor balcony. The rain and wind were howling that night and afterward, she told everyone that I had been blown off the building by the storm. To my horror, my husband believed her without question.

When I opened my eyes again, I found myself reborn, back before my sister-in-law gave birth. The realization hit me like a tidal wave—I had a second chance. A chance to change everything, to protect myself and most importantly, to make her pay for what she did. But as I prepared to exact my revenge, digging deeper into her actions, I uncovered a darker, more sinister secret hidden beneath the surface. A secret that threatened to unravel everything I thought I knew.
