An Office Association (слэш)

Severus Prince is the Head of the Prince family and also a respected Auror of the Auror corp.
Meanwhile, Harry is born in a normal family, raised by love, and decided to become a Healer.
He has the biggest crush on Severus, and one day, Severus flirted with him, asking him on a date.
Harry is thrilled beyond comprehension, thinking his lucky days has finally come. What he doesn't know is that the day before, at a gathering, as he was drunk out of his mind, he vented to Ron for the 1000th time about "how soft Severus hair is", "how elegant his hand is", and "how Harry want to kiss those thin, beautiful lips".
All the while Severus was standing right behind him with Sirius and James, both smug and slightly elated because the brightest (and most handsome) Healer in the Department fancies him. And because Sirius and James looked like they had swallowed a bunch of flies.
So the next day, Severus acted on his impulse and teased the boy, asking him on a date.
Harry is on cloud nine, blabbering and figetting the entire time, and Severus thinks the boy was cute.
Until he is fucked senseless into the mattress.
They date, later.
And James goes fucking mental.
