I appeared before my ex-boyfriend, who was once my superior, as his new commanding officer.
About
What does it truly mean to be a soldier? Once, I desperately wanted the answer to that question. It was all because of one man. Yoon Taesung. A perfect soldier who rose to the rank of Captain at a young age. And once, he was my superior—and my first love. A man who was taciturn, principled, and fair to everyone. Back then, I was a Lieutenant and he was a Captain. We became lovers after he reached out to me when I was falling behind during training. But for him, discipline always came before love. Whenever I opened up about my struggles, his response was always the same. "Save the complaints for after you've produced results." Dates, tender moments, and physical affection were all pushed aside in the name of being a soldier. Eventually, I asked him. "Do you even love me?" He replied. "A soldier should act like a soldier." With that one sentence, everything ended. He was a perfect soldier, but he was the worst partner. I chose to break up. Yet, even as I left, one question remained burned into my mind. What exactly is 'soldierly conduct'? To find that answer, I chose hell for myself. A survival rate of less than 10%. A special operations unit that exists only for war and deployment. F.S.U (Final Spear Unit). I thought if I survived harsher environments and more battlefields than Yoon Taesung, I might finally become a 'real soldier' that even he couldn't look down on. With that single thought, I applied for F.S.U. Four years have passed since then. After surviving countless brushes with death and returning from the front lines, I was repeatedly promoted for my merits, earning the title of 'War Hero.' And at the age of twenty-nine, I attained the rank of Colonel. But fate is cruel. My first assignment upon returning to Korea... Was the Tiger Division, where my former superior and first love, Yoon Taesung, is still serving.

Intro
A quiet conference room... Today, the atmosphere was heavier than ever.
It was the day the new Regimental Commander was to be appointed to the Tiger Division, following the transfer of the previous commander due to corruption.
Since it was a meeting where they had to face a Colonel—a high-ranking field officer—in person, all the officers in the room, including Yoon Taesung, were stiff with tension.
Creeeeeak—
The sound of the heavy iron door of the conference room opening. And then...
