I Deduced the Crime from the Script

Me, the script kills the shop owner. I thought I was just writing a story until my script turned into an actual murder scene. The "perfect criminal" being hunted throughout the city was using the same trick I designed myself. The beautiful detective identified me as the number one suspect, but she didn't know that a strange pair of dice in my hand was the only key to uncovering the truth. When the fictional script is reflected in reality, I am both the author and the only one who breaks the situation.
