"Commander, are you alright?" Hugo asked with concern when he saw Thirteen.
The young man visibly struggled to walk, relying on the hallway's wall to support him as he moved forward.
"I'm perfectly fine, Hugo," Thirteen replied calmly. "This is just the body's natural reaction after some… intense physical exercise."
"Then please don't exert yourself again, Sir," Hugo said. "Everyone looks up to you, so if they see you like this, they will feel anxious."
"Well, you have no choice but to get used to it. I'll be like this for at least a week," Thirteen replied, walking at a steady pace although his legs were shaking a bit. "Our enemies are strong, so everyone must do their best to train every day and raise their stamina as much as possible."
Erica giggled after hearing the young man's reply.
When the teenage boy woke up in the morning, his hips ached a bit.
