Remus Lupin/Sirius Black

He stood there in his long, black and dirty hair with a smile that teased the viewer.
Sirius face was aging much faster than his childish smile and his grey eyes, the eyes of Black had a glimpse of something he spotted as a light.
Azkaban had broken so many men down before but Sirius was alive, breathing and smiling towards him.

How dare he be fine.

"How did you dare leave me?" I yelled filling Grimmauld Places silence.
He put his hand on my heart and for the first time I saw sadness in his grays.

"I never did"
