Doo-sik, the super agent who can fly and has good morals despite his job, (which is similar to an assassin) he also keeps himself tamed and foreboding around others because of the nature of his job, but is actually a sweet, kind, and likes to make certain jokes type of guy. And even though he acts experienced and professional, Doosik is a shy and admiring type of person when it comes to love which is rare with his line of work.
