Mako walked over to Bill to find him lying flat on the ground and breathing quite heavily as if he was gasping for air.
"Are you alright?" Mako asked with concern as he approached his best friend.
Bill decided to play a little practical joke on Mako as he didn't reply to Mako telling him that he was alright, but rather he just started staring at him with his eyes wide open and a serious look with no comment made by his lips.
Bill's sudden behavior caused Mako to panic as he thought maybe something was wrong and Bill needed help, making a face full of tension and worry.
However, he could only contain his laughter for a couple of seconds before he busted out laughing out loud at the Mako's priceless face.
Bill's laughter relieved Mako's heart as he confirmed that he was all okay and was just messing around. He was honestly in shock as he thought that maybe something had happened to him internally and that the patrolling officer would have to step in to save him.
