Story
Everyone at work loves Mamoru, because Mamoru never says no. Replacing lightbulbs, carrying boxes, taking over an impossible client from a retiring colleague… He'll do it all, and it's earned him the nickname "Prince of the Office." This glittering extrovert's opposite at work is Kurone, a quiet woman in another department who soaks up her boss's senseless mood swings with a blank stoicism.
