It's as if a switch was flipped on Midori's head and he smiled, a creepy grin as if he was planning world domination. Hiroshi smiled back at him, but the smile in and of itself was filled with ulterior motives since he would be using Midori to get out of there. There was no way he'd punch the slat of wood in front of him... that's why he could only depend on Midori who is more muscular and overall physically stronger than him.
"That's a good idea!" Midori cheerily said and without thinking twice, brought his hand back and swung it hard. Thump. The wooden slat in front of him seemed to crack a little.
