My Ex Changed My Door Lock

My ex-girlfriend broke up with me but refused to move out right away.

She asked to crash at my apartment for a few days until she could find a new place.

Thinking about our three years together, I soft-hearted and gave her a temporary smart-lock passcode.

But when I got back from my business trip tonight, I couldn't get in.

The screen on the smart lock read: Access Denied. Incorrect Passcode.

I pressed the doorbell.

Inside, I heard the rustle of slippers, followed by a man's annoyed voice.

"Who the hell is it at this hour? So annoying."
