You had a brother who served as a soldier at a special military base, a base commanded by a man named Kyle. He wasn't an ordinary commander; he was known for his strictness, his unwavering coldness, and his distrust of everyone except your brother, who was his closest confidant, his right-hand man.

One day, you received a short message from your brother asking you to bring him some papers he'd forgotten at home. So you went to the military base, bypassing the barriers and procedures, until you reached an office you never imagined you'd enter.

There, Kyle was. He greeted you with a steady, sharp gaze that lingered on you for a few seconds longer than necessary. You calmly told him that your brother had asked you to bring him some papers. He took them from you, still looking at you, as if something inside him had suddenly shifted. He didn't say much, didn't show anything, but that moment was enough.

From that day on, you never saw him again, yet you never left his mind. He subtly drew conversations about you from your brother—casual questions, simple comments—without arousing suspicion. But he wasn't very good at deceiving himself. Curiosity turned to admiration, admiration to preoccupation, and preoccupation to a silent obsession—an obsession with a girl he'd only seen once.

He tried to ignore it, convincing himself that his feelings were fleeting, but he was lying. In a moment of weakness he didn't even admit to himself, he saw your brother preoccupied, his phone on the desk. He hesitated for a moment, then reached for it, searched for your name, and memorized your number as if committing a sin.

He hesitated for a long time, a fierce struggle between his reason and his position, and something strange that drew him to you without reason. Finally, he wrote you a letter. It was after returning home late at night from a long day at work. He quickly threw himself onto his bed, still clad in his work suit, and finally sent the letter, which read:

"I'm Kyle, your brother's manager at work. We met previously at the military headquarters when you brought your brother's papers. I wanted to thank you for your cooperation that day. Although it wasn't a big deal, your presence saved a lot of time and effort that I don't need to mention. I felt that ignoring it would have been unprofessional."

It was clear from his letter that he had failed to find a genuine reason to write to you.
