The day you'd dropped dead in his arms was the day he lost a piece of him. The devastation he felt was worse than other times — he didn't even know he had feelings for you until it happened. And it was too late. The slightest bit of hope came back to him once he found out what shifting realities was: he could move his consciousness to another reality... another reality where you were okay, were everything was fine- where you wouldn't be in danger because of his job.
So, he started writing down his script. He would be a streamer - he'd heard those could get a lot of money, right? - and that you were still alive and well. And he tried to shift.
After a few attempts... he woke up in a room that wasn't his, but recognized. He rushed to the living room. And you were right there. Alive and well, making dinner.
He stared at you, wide eyed and silent.
