A/N: Hey, sorry for the long wait! And thanks for all the reviews and follows/favs! Means a lot!

Dear Sirius,

Say something. Anything.

Look me in the eyes, please.

Just don't ignore me anymore. That's all I need for now.

Can you do that for me?

I can't go on like this anymore.

I don't want to break down every time I see you. Every time that you pass me by like a stranger.

Please don't leave me.

Please stay.

Because I don't think I can go on like this, missing and longing for you so much.

Katherine thought of what she had wrote in her diary just the night before while she stood by the door of the Alchemy room, waiting. Sirius stood up from his new spot at the back of the room and collected his things in his knapsack. He kept his eyes down and his hands in his pockets just as he always did. He waited for the crowd of students by the door leaving the room to decrease. He was the last one out except for Katherine who was still waiting by the door. And like every class for the past month now, he passed by without so much as a glance in her direction. And then came the pang. The shooting pain through her poor heart that fell to her feet like the moment on that late night when the tears came from her eyes endlessly.

It was masochistic and she knew it, but every morning she couldn't stop herself from waiting by the door, waiting for him to leave her behind again. Waiting for the pain to hit her and remind her of what no longer was hers.

She tugged at the silver key around her neck, a charm for her sadness. She remembered sitting by the blossom tree that he no longer visited, writing endless messages in her diary to him. Writing everything she so desperately wanted to tell him. The things she should've told him sooner, before it was too late.

It was spring now, and the blossoms fell softly on the grass in the wind. Everything about it reminded her of him, everything about them. The times they sat by the base of the tree and he pulled a strand of loose hair behind her ear. The times they lied in the snow under the shadow of the tree, freezing cold but not caring anyway. The times they watched the blue Jobberknoll flit about the tree while he held her close.

She remembered the pain of the night that everything ended. The night she sat crying on the cold floor in his white knit sweater that she never gave back, breathing in his scent of wood and fire, trying to hold on to any piece of him left with her. She remembered how Lily finally found her trembling on the floor by the window and with the help of Marlene got her into bed, warmed her up until she at least stopped shivering. But the tears never stopped until she finally fell asleep.

Nothing any of their friends had said or done could get either Katherine or Sirius to talk about what happened. Not when Lily pleaded with Katherine to tell her and hugged her tight when she cried. Not when James asked Sirius again and again to tell him what happened, to let him help him. Not when Lily came down from the girls' dorm to the common room one day in the middle of the night after witnessing Katherine crying herself to sleep again. When she yelled at Sirius, while James held her back, to tell her what happened, to fix things. But all Sirius could say in a broken voice was, "I'm sorry." because he was and because there was nothing he could do to fix things.

For the first week, it went on like this, crying and running away, the broken pieces of both their hearts shattered lying across the floor. Katherine stayed in the dorm most of the days and Sirius spent most of his out somewhere she didn't know.

After the first week, Lily forced Katherine out of the dorm without another word and chaperoned her one the way to and from each class, not caring if it made her late to some of hers.

"I'm not letting you waste away your life in that dorm, just because some guy dumped you." Lily said one day on the way to Potions.

"But he wasn't just some guy." Katherine reluctantly stepped into the classroom where Sirius sat in the back, having an argument with James.

"I know he wasn't. I know he will never be just some guy. He was probably the guy. But you are the you. And I don't want you to be hiding away because it hurts to see him. I want my friend back not this sad and depressed version of her, will you give her back to me?"

"I can try."

And she did try. She stopped wearing his sweater when she slept because it only made her miss him more. She stopped staying in the dorm all day and went with Lily to all their meals in the Great hall, regardless of the fact that Sirius sat only a few seats away with James next to him. She stopped crying herself to sleep and actually slept during the night. She stopped avoiding the places she knew he would be, like the common room or his favourite spot in the corner of the library, or the quidditch pitch. She even went to their game with Ravenclaw with a big smile on her face and cheered for Gryffindor like she did before the break up.

Although this pleased Lily to see Katherine in better shape, she didn't know what was really happening. She didn't know that when Katherine didn't wear his sweater to sleep her heart froze in her body without its warmth. She didn't know that though Katherine went to meals properly, she never ate a single bite, just acted like she did. She didn't know that while Katherine did sleep at night, in the early morning she would go out the blossom tree and torture herself with the memories she refused to erase. She didn't know that Katherine still couldn't walk to that corner of the common room where he first kissed her, or that she still couldn't walk down the paths of the grounds where they had walked hand in hand so many times. And she didn't know that even though Katherine looked better and sounded better, her smile wasn't as real as it used to be.

It wasn't just hard for the Katherine and Sirius but for their friends as well. Lily and James hadn't been able to eat together during meals in weeks. They were on constant Katherine-Sirius watch and Marlene, Peter and Remus were starting to feel very awkward as their group of friends fell apart.

That was the reason why, on another sunny day at the end of April, Sirius and Katherine decided to at least attempt at being in each other's presence and talking for their friends' sake and sanity.

They all sat together at meals and in the common room to study or talk sometimes and things weren't as bad as they could've been. At first, no words came out of either of their mouths, but eventually some of the easiness of when they first met as friends, came back to help them. They talked and they laughed and spent time together with their friends, and their friends were finally feeling better like their gang was back together again, at least before their last year at Hogwarts ended.

But only Katherine and Sirius knew that things were not okay. That they never stayed in a room alone together, without their friends. Sirius never sat next to her like he used to and she never asked for his help to study anymore. They talked but the only things that ran through their heads were the words that they said to each other that dark night in March. They sat opposite each other during meals but their eyes never lifted off their plates to look each other in the eye. To see the pain still left there.

A/N: Promise I will have one or two more chapters up this week! Please review in the mean time! I'm working hard on the end and I need your strength! :)
