From Manga Pirate:
"Once upon a time, I was the fucking boss"

Choo, a middle-aged restaurant owner, is being ripped off by a couple of no good teenagers! They might think he's a nobody, but there is a past to him that nobody knows. And nobody should know.

From Vendetta Scans:
One thing is for certain - if you exercise violence, that violence will return to you in any shape or form.

The man who bakes flour-based food and runs an eatery, has a darker past than anyone could ever guess.

...unless you see the name of his store.
