Draco's a prefect. And Harry is a pain in his ass.

He's doing his usual rounds, making sure nobody's in the wrong area. He decides to make sure nobody's sneaking around the restricted area in the library. Seeing Hermione and Ron in the library without Harry made himsuspicious, and Draco soon found him, the idiot took his invisibility cloak off too early.

"Come onnnnn, Dracooooo," Harry complains, looking to his friends for backup. "I'm the boy who lived! Cut me some slack, please?"
