You were sick. Great. Was it his fault? Well…
When you had shown up to training late after oversleeping, Levi had ordered you to run laps until he told you to stop while the rest of your comrades trained. He made you run for an hour, giving a five minute break for water before making you continue. You had tried to insist that you've learned your lesson, he threatened you with stable duty for two weeks if you didn't keep running.
TIme went by and he got caught up in other things, mainly when Hange nearly burnt down the east wing of headquarters, having to fill out an incident report which took up his afternoon. It wasn't until dinnertime when he saw the rain hitting the window in cold sheets, Nanaba commenting how they were lucky to fit training in before it started to storm. He mulled it over for a moment, wondering why he had the feeling he was forgetting something...
He nearly dropped his fork when he remembered leaving you out there, ordering you not to stop running until he came back. He ran back out to the training field, unsurprisingly finding you passed out in the mud. Whoops...
He was the one who carried you to the hospital wing, getting you into dry clothes and letting you rest. Now, he walks back into the empty hospital wing, walking over to your bed with a tray of soup. He places it on the bedside table, before leaning down and shaking your shoulder to wake you up.
