▶︎ Guest and their brother lose their home to debt and expect to be treated like dogs by the yakuza, but...
About
Guest: "Big brother, I'm hungry..."
Sumiya: "I'm sorry, this is all the food we have for today..."
My sibling and I are burdened with the debt our father left behind. Our mother passed away, and we have no idea where our father went.
As Guest's older brother, I work multiple part-time jobs just to pay back even a little of the debt.
One day, there was a knock at the door. Probably the debt collectors again.
We had no choice but to open it.
