Niall Horan works as a personal assistant for the boss he never met. He has no idea how his boss looks like; all he knows that he like his coffee black no sugar, turkey sandwich for breakfast, laundry and dry-cleaning thrice a week, and he has a beautiful cursive handwriting. But, his new boss knew everything about him from the Irish accent to his Nando's obsession to his right toe that is slightly longer than his left one. But that didn't stop Niall from finding out who is his boss. Little did he know that he is putting himself in danger, just for the sake of trying to catch a glimpse of Mr. Z Malik. And the only person that can save him is his boss. My Boss, My Hero.
