Harry Potter has a problem.
His friends knew it. It's easy to see it - in the way Harry frowns and curls his lips as he nonchalantly walks down the halls of Hogwarts; in the way Harry's dinner plate remains untouched for several consecutive meals; in the hour after hour he spends flying solo and in Hermione Granger's scolding of him for not devoting enough time and energy to reviewing NIEM.
"Poor Harry," they thought. One imagines that he is obsessed with some noble but dangerous cause, such as preventing the emergence of a new generation of Dark Lords, or becoming the best and most fearless Auror the Ministry of Magic has ever produced, or other serious issues involving the future of wizarding society.
But the Gryffindor's problem was much more than that - in fact, it was much more serious than one might imagine. The question slowly tormented him, driving him crazy and keeping him awake all night. Harry even missed the time with Voldemort, because when dear old Tom was still there waiting for a chance to kill him, things were not as complicated as they are now.
Because, unlike what a duel with Voldemort would require, his current problems were far more than a spell and a few doses of courage could help him solve.
The problem with Harry Potter is that Draco Malfoy's eyes widen when he kisses.
