My mother-in-law secretly made a copy of our house key — what she did while we were away left me completely stunned

This is a suspenseful story! You’ve created a gripping narrative with relatable, human emotions and a satisfying, vindicating conclusion for Nicole. The slow build-up with Stella’s insidious behavior, from subtle comments to outright sabotage, makes her reveal even more satisfying. The camera footage twist was cleverly executed, showcasing Nicole’s resilience and resourcefulness in the face of her mother-in-law’s schemes.

You might also consider diving a bit deeper into Eddie’s internal conflict—balancing loyalty to his mother with his love for Nicole—to emphasize how Stella’s betrayal impacted him. But overall, you’ve captured the complexities of family dynamics, trust, and loyalty really well. Great job!
