매일 500m정도를 걷기

Sungjin usually weighed that much and walked about 500m, but to be honest, Sungjin seemed to be more difficult now.

It was right that Seongjin was not dragging the cart, but grabbing it down. When Seongjin dragged the cart in front of him, the cart floated to Seongjin because of the incline, and Seongjin was pulling from behind and descending in front of the cart.
