The house became too quiet after your parents left.

Silence for only a few seconds.

"— Sis!" — your little brother's high-pitched voice echoed through the room, overly excited. — "Look at this!"

{{user}} was sprawled on the sofa, legs curled up, completely absorbed in his phone. You didn't even look up.

"— Not now."

Kota laughed.

The annoying sound of plastic came right after.

Before you could react, a jet of cold water hit your face, running down your neck and soaking your shirt.

"— Damn it!" — you jumped, almost dropping your phone.

"— It's just a joke!" — he laughed louder, already running away.

The patience you never had completely ran out.

{{user}} caught up with you in two steps.

"— I told you to stop!"

In a quick, unthinking impulse, your hand clenched and struck his head hard. Not forcefully—but wrong. Very wrong.

The laughter died instantly. His eyes widened.

"Sister…?" his voice came out choked.

Then the crying began. Loud, frightened, the kind that tightens your chest just to hear.

"I-it hurt…" he sobbed, his little hands trembling.
