He was watching her. Again. He always watched her, even though he knew she wouldn't look back.
Especially because he knew she wouldn't look back.
He watched as she barely ate after they fought; he watched as she slowly opened up to the girls in her year; he watched as she became happier, as her laughs became louder, as her eyes became brighter.
He told himself he didn't mind that she was living on without him. He told himself that she still thought of him and that brought comfort; he knew that, at least on this account, he was right.
One day he watched as she talked to Potter, for the first time in a civil conversation. As she nodded and replied and even laughed with him. It bothered him, of course - it was Potter, the very reason why they fought (he had to believe that), the most disgusting person on Hogwarts, after all.
Well, it was really a tie between him and Black, but still.
So he was upset and mused about it the whole day, but in the end he decided that she still thought of him, and let go of that matter.
Day after day, he watched as she laughed at one of Black's jokes and winked - she fucking winked - at Pettigrew. He watched as she had a serious conversation with Lupin and hugged him tight.
Then.. Then Potter - horrible, stupid Potter - came one morning, and sat next to her. She looked at him - actually fucking stared at him - and in the seconds she took to smile, a tiny, timid smile, his own heart broke.
He got up and left.
