Look more carefully, when he Tian picks up and inspects the underwear, the torn hole was drawn in toward the right under side of the underwear. It's shaded in gray. Also when he Tian stretches it out, you can see the jagged seams, meaning that wasn't the properly stitched seams of the underwear hole. Plus the underwear hole should be located more upward, either to the left or right of the fly area, not that low.
Mo has a hole in his undies.
Why r people asking about hole in the undies?
