This will probably turn out to be a very weird one-shot about … grief?
It had been a beautiful day in the middle of April. That day. It had been warm and sunny, the sky had been blue, the grass had been soft between his toes and laughter had filled the big, lush garden. It all seemed so far away now, so long ago. Like it had happened last year, instead of last week. He had felt so tired since, since that day. His entire world had crumbled before his eyes when they had told him. He had run, to where he didn't know. The only thing he had known was that he had to get away, away from there, away from her, away from that day. He had ran for hours and hours and when he had fallen on the forest floor, he had not wanted to drag himself from the ground so he had stayed there the rest of the evening and the beginning of the night. When the moon had disappeared but the sun hadn't shown itself yet, he had stumbled to his feet and he had started to run again. He had kept running, not allowing himself to slow down, not allowing himself some rest. Not until he had lost her. Not until she had left him. But she wouldn't. She was stubborn, like she had always been. Up until that day. She kept him going, just like she had always done. Up until that day.
They had been so happy, before that day. They had been everything he had wanted. They hadn't been what she had wanted, but it didn't matter to them.
They had been scandal, especially on that day. No, he thought. She had been scandal, they had been… What had they been, on that day? He didn't know, didn't want to know. The only thing he wanted to be was away from her. And so he kept on running.
She had been the spark to ignite his life. She had made him human, transformed him from an antagonistic animal into an actual human being with feelings. But now she wasn't there to help him anymore, so he kept on running. She had helped and given him so much, he wouldn't have ever been able to return the favour. He had tried, but it had never been enough; and now it was too late. All because of that day.
He didn't want to be without her, he hadn't been good at being alone ever since he met her. But he was too afraid to go to her, it wasn't what she had wanted anyway. He didn't know what to do, she had been his guide and now he was lost. So he did the only thing he knew, the only thing he was good at. He kept running.
