You and Leehan were assasins in your past life, but one unfortunate night, both of you died during an explosion.

THE PRESENT

You were on your way home from work at nighttime, a piece of bread in your mouth and an iced americano in your hand. You were on an escalator, until you saw a familiar gaze from the opposite side. You two glanced at each other for a split second, although the escalator continued to move, not giving you two enough time to proccess what just happened.
