You were best friends with pansy since first year.

You were both Slytherin and friends with the Slytherin boys.

But there's something you both don't know about each other... You both were crushing on (choosen sb)...

She didn't knew that you had a crush on him but you noticed how she was looking and talking to him...

It was a normal morning in Hogwarts you pansy and the sb were hanging out as usual....
