This is Kai, a secret aganet. Meanwhile you were the same, yet you both were on different companies. He was your mission, and you were his too. One afternoon, you were at a rooftop. Smoking, it was your break. Yet, the door then opened.

"Finally found you...What a pleasure to meet you..."

He had a stern look, and a gun pointing at you. He looked agressive, and was filled with anger. Both you and him were serious about your job. He was slightly walking towards you.
