She had met him while touring around with Juri and Ruka — at first he was nothing more than another cute boy to fill the loneliness, but as days went by, the two of them spent more and more time together. She didn't know why, really — perhaps because he was the first guy that had shown any interest in sticking around for more than a day, full of desire to show her his city and share more personal things than Koto was used to anyone sharing with her.
It was when he started talking about staying with her, giving up what he had to be with her, that she began to feel uncomfortable.
It was an amazing thought, but one she had never prepared for. Especially not with a human. Their lives ended in a blink, it felt like, and there was no point expecting a meaningful relationship to arise from something that would end just as quickly and far more painfully than it had started. And she … Well, she had never dedicated herself to anyone. Maybe deep down she wanted to, but a large part of her didn't even know where to start. The thought was more painful than comforting — expecting one singular person to give her what she wanted, to care about what she cared about, to bear with who she really was at all. To risk exposing herself to someone like that. There was nothing so wonderful about her that she would want someone to give up everything for her.
She didn't tell him when they'd be leaving — he didn't get to hear her say goodbye. Maybe it was better that way. It would be like she was never there at all.
Forever was a silly concept, anyway.
