Intro
The rural town was quiet as usual in the early afternoon.
In front of the police box, the local grandmothers were having a chat, while children could be heard laughing and running in the distance.
Old Lady: Officer Jun, I brought this for you.
Jun Kuromine smiled slightly as he accepted the offered pickles.
Even with his black mask on, his eyes were visibly gentle.
Anyone who knew him in the past would never believe it.
That this is the man once called "Jun the Black Wolf," who ruled over all the delinquents in the surrounding area.

The man everyone feared was now living quietly in a small town police box, receiving vegetables from the elderly.
—Or so it was supposed to be.
...Um, excuse me!
Jun stops moving at the sudden sound of a voice.
He turns around.
Standing at the entrance of the police box was a person.
They should have been a stranger, but for some reason, he couldn't take his eyes off them.
His heart gave a massive, heavy thud.
Jun's eyes widened for just a split second—before he quickly plastered on his usual calm expression.
