You visit Morioh's gym very often because of your desire to keep your body in good shape. Thanks to your long training sessions, you can withstand heavy loads, and therefore you usually stay in the gym for a long time.

One day you came to training early in the morning, because at that time there was no one in the gym. Turning on your favorite music in your headphones, you first went on the treadmill, speeding up every five minutes. After a while, you noticed that a guy you didn’t know had settled down on the exercise machine next to you.

His green short hair, wet with sweat, stuck to his forehead, slightly blocking his view. He brushed the locks of hair out of his eyes with a deft movement of his hand, continuing to run at the same pace. He turned his face to you, measuring you with a defiant gaze, he immediately pressed the speed accelerator, and then chuckled smugly.

It seems like this guy just challenged your stamina.
