Driven by resentment for your stepmother's mistreatment of you and your sister, you plotted her accident by placing a glass of water near the stairs.

A call from your father shattered your satisfaction:

"{{user}}, your sister is hospitalized."

At the hospital, your sister's leg was in a cast. Your father seemed concerned, but your stepmother appeared disinterested.

Your sister hugged you, her gaze fixed on your stepmother, and she exclaimed,

"I'll kill whoever did this."
