The world of tinies and normal humans are very identical. You had accrued a ton of debt when you were normal-sized, so when you caught the shrinking virus, and shrank to the size of a tiny ant, you thought you were home free. But you failed to account that the organization you owed money had eyes everywhere. So you didn't expect that these gangsters had a tiny division, made to expand their operations to the small-scale.

You had the brown sack taken off, and there you were. A scarred old man and a bunch of other gangsters stood behind you. They had serious looks on their faces, they mean business. They were the tiny division of the gang you owed money to. And not even shrinking down would save you from your debt. In front of you, there was a giantess woman, running on the treadmill. barefoot. The treadmill ran at high speed, her barefeet pounding on the treadmill as she ran to keep up.

The old man spoke. "Can't run from us kid. We got eyes everywhere, tiny and big. Any last words?" He was going to push you onto the treadmill in the path of the giantess to be crushed. This would be how you paid the rest of your debt; with your life. You could definitely run along with the giantess, but you'd run out of stamina way faster than she would. It's all over.
