It wouldn't have been the first time this had happened. Sirius has ditched our planned dates more times than I could count on a single hand. This time I spent an hour and a half sitting on the castle's steps waiting in the cold.

Yesterday we agreed to leave the school grounds at 10:00 am and make our way to Honeydukes to try some Bertie Botts. The stress of school had started to catch up to us. The trip was supposed to be a tiny, fun getaway for that. Even if it was for a few hours.

It's nearing noon and I can't take the cold any longer. I walked back into the castle and headed to the library. Now there's no point in not studying, might as well try to stay caught up while I apparently have the free time.

I would be fine. By the time Monday comes around, he'll look at me with those pleading brown eyes. Hints of guilt will peak through as he apologizes. Maybe he overslept, sometimes the boys lose track of time. It's possible he lost track of time this morning, too engrossed in a little prank he's planning. Or maybe Mary asked for help last minute and he's just too polite to say no.

The last one has been happening more and more recently. She wanted someone to go over her essay and Sirius just happened to be in the gryffindor common room at those moments. Or other similar little white lies.

When he first mentioned her I asked who she was, I was curious to know who was taking away the times Sirius and I had planned out for just us. He told me, Mary Macdonald like I should have known who she was, like he introduced me to her just like how he did to his other friends.

But no, I didn't know her. I also didn't know if I wanted to or not.

He told me the basics, she's a gryffindor like him and she's more friends with Lily than she is with him. Other than that he dodged and avoided as many questions as he could, especially when I asked why Lily couldn't help with her studies. Eventually shutting me up when he told me that he loves me and I have nothing to worry about. That I was paranoid.

I walked into the library and the smell of old books hit me. My nerves were calmed a bit as I walked through the tall shelves of books, making my way to a section I became familiar with this year. I had an essay due in History of Magic at the end of the week and it couldn't hurt to start today.

The smell of books started to be drowned out by another familiar smell. The sound of hushed whispers coming from the other side of the shelf. I followed the smell of Sirius' cologne and the sound of his laugh that's a little too loud for the library. As I rounded the corner I stopped dead in my tracks. There he was sitting in the library with -I'm assuming- Mary Macdonald. Sirius didn't even have attire around him that would indicate he had plans to go outside.

His back was to me, and they were once again in a laughing fit. When I cleared my throat, Mary looked up at me in confusion at first, which morphed into recognition, then concern. Sirius turned around and I didn't give him a chance to speak.

I spoke with a clear voice, "Can we talk real fast?" Without waiting for a response I turned around and walked behind the shelf once again.

While waiting I heard Sirius tell her that he'll be right back and the shuffling of him scraping the floor with the chair. I could hear the dragging of his feet, and his head probably hung lower than usual. No doubt that he was aware of the anger that was bubbling inside of me.
