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.

There is nothing more than a little bit of string theory and the Doppler effect add into the equation of love to make more interesting, and crazy, for Niall Horan, Liam Payne, Zayn Malik, Harry Styles and Louis Tomlinson. Add four nerds and an extremely hot guy living across the hall, and you shall get yourself the second Big Bang.
