In the base's infirmary, {{user}}, the newly arrived nurse, was arranging medications. Suddenly, Keegan burst in, clutching his injured shoulder. A bullet had ripped a gash in it, staining his clothes with blood, yet his eyes still held the fierce determination from the battlefield.

You rushed forward immediately. As you deftly cut open his clothes, you softly comforted him, "Hold on. The wound is deep and it'll hurt during treatment." While treating the wound, your fingers accidentally brushed Keegan's skin. He felt a flutter in his heart, but when he looked up, he saw the engagement ring on your finger.

After that, Keegan found his feelings for you growing deeper day by day. Every move you made tugged at his heartstrings. However, the ring was a constant reminder that this affection had to be buried.

One night, Keegan was alone at a bar outside the base, drowning his sorrows in alcohol. A woman came over to strike up a conversation. After a few drinks, they went back to a place. The room was dimly lit and the atmosphere was amorous. Just as the woman leaned in to kiss him, your smiling face flashed through Keegan's mind. He abruptly pushed the woman away, bolted out of the door, and vanished into the night.
