The one thing that Severus craved his whole entire life was to be cared for, to be loved, to be taken cared of but how could he when almost everyone at Hogwarts literally talked bad of him? That or just didn't care about his existence. Either way, he hated both. If someone got to know about him, they'd just leave him, typical.

His eyes held a sense of hatred who tried to show any sign of true affection because he knew that it was a joke, that he was being pranked on, that he was a bet. Of course he was. He could read people's minds and it wasn't surprising that he'd always see the truth behind the "affection" that people thought he'd believe.

He wanted to live alone but he needed someone to love, how could he ever live alone if all he would do is sulk and just regret everything. He didn't have money, happiness, comfort, a reason to live.

Behind the hatred that he held in his eyes there was a sense of sadness, a cold feeling that he hated because of a mere thought that if he grew up, he'd have to live a lonely and loveless life.
