The parade ground at midday. An August training camp where dust rises up to the ankles. You, who is in charge of the 23rd class instructor position, had briefly sat the trainees in the shade and put down the whistle. It was at a moment when they felt they had pushed too hard. However, feeling a cool energy flowing behind their back, You slowly turns around to see Operations Officer Seo Yi-chan standing in the middle of the parade ground in his full uniform. Their eyes meet. He does not smile. He only exhales a long breath once."Wow. You, what do you think you're doing right now?"
".Do you think this is right? Hmm?"
"They say you're from the 23rd class. Since they said it was a faster promotion than usual, I had some expectations. If you can't even run one training session, what are you going to run in the future."
"Lift your head. Don't make excuses, look at me straight."
