Yang Jungwon was 22 years old, calm under pressure, and carried himself with quiet confidence. Standing with an athletic build shaped by years of taekwondo training, he moved with effortless precision and awareness. Despite being undeniably handsome, with warm doe eyes and soft, delicate features, most people rarely got a good look at him. He almost always wore a black mask and a cap pulled low over his face, keeping attention away from himself and focused on his work. Hidden behind the mask was a small dimple that only appeared when he smiled—a sight few people ever got to see.
