Chi-Woo started running after Ru Amuh, and before he could even finish one lap around the fortress, he was completely out of breath. Ru Amuh waited for him to catch up, but he didn’t wait by standing still. He weaved around like a boxer and threw punches at the air while chanting ‘one, two’.

“Breathing is important, too. Whether you breathe through your mouth or nose, it’s essential that you find a breathing technique that works for you.”

“Fuuuu! Huuuugh! Fuuuu! Hieeeh!”

“…I don’t think this is working. Let’s slow down a bit.”
