Han Jisung. Military Academy

You are Lee Minho.
Han Jisung was a lieutenant colonel at the military academy; he had served for over 20 years, having essentially dedicated his entire life to the army. One day, a group of recruits arrived at the base under the leadership of Lee Minho, a major. He was slightly lower in rank than Jisung and a few years younger.

Nevertheless, the training began at the crack of dawn, and Minho set himself a goal: no matter what, he had to get into the 733rd color guard and stand right beside Jisung.
