I remembered that night when my brother covered my sister's mouth and nearly suffocated her, but he still wasn't reassured.

"But..."

We were talking at the doorway when suddenly there was a "crack" sound from inside the room.

The sound was just like the noise my mom made when she broke chicken bones while cooking.

My sister's cries of pain turned into howls, "It hurts! It hurts so much!"

"Little sister! Save me, please save me, I'm going to die."

I panicked and rushed in, desperately trying to pull my brother off of her.

"Get off! Let go of my sister! Can't you hear her crying?"

My brother, caught up in his excitement, raised his hand and swung a punch at my face.

I fell to the ground, my ears ringing, my nose feeling like it had broken, tears uncontrollably streaming down.

My mom also ran in, "Crying, crying, all you know is how to cry! So what if you were taken advantage of by a man? What's there to cry about? Pathetic thing!"

I endured the pain and got up. My brother happened to change positions, revealing my sister underneath him.

I gasped, screaming.

"Mom, look at my sister's leg!"

My sister's thigh bone was bent at an unimaginable angle.

It seemed to have broken in the middle, and the bone in the middle of her thigh was protruding, almost piercing through the thin layer of skin.

My brother lifted her leg, which had gone limp, and wrapped it around his waist. The flesh in the middle of her thigh drooped as he moved, almost forming a corner.

My sister's expression contorted, and her fingernails dug into the bed, drawing blood.

"I don't want this! Let go of me!"

"You're just an animal! Why torture me? Why?"

I saw an excited smile on my brother's face, full of malice and gloominess.

How should I put it?

It didn't seem like the mischievousness of a child, but rather the cunning of an adult.

Before I could look again, his expression changed back.

My sister cried and cursed again, and then she started coughing violently, as if she was about to suffocate.

"Mom, if you keep this up, my sister will die! Don't you care?"

My mom didn't move, seemingly still weighing the situation.

I shouted again, "What about the lives on my brother's back? Don't they matter to you?"

Only then did my mom panic, trying to persuade my brother in a gentle and kind voice, but my brother didn't appreciate it.

He intentionally tortured my sister slowly, rocking back and forth, slowly.

"Mom, I haven't had enough fun yet, I feel uncomfortable."

My brother's voice sounded aggrieved, with a childish petulance, "She always squeezes me with her legs, no matter what I say."

"So I broke her leg."
