Sleep would heal him more than food would. His body just needed to rest. He didn't like worrying her as much as he was but, unfortunately, Maru didn't know how to fix that. He wanted to tell her she didn't have to watch over him, but it was her choice to do that if she wanted, he couldn't make her do otherwise.

So when she nodded and agreed he should sleep, Maru felt himself relax a little bit. He would sleep.

He tilted to the side to lay down and let his head come to rest upon her leg, his eyes closed. Maru remained curled up, legs tucked in, one arm wrapped around his middle. "... I'll sleep." He said softly, voice quiet and already sounding half asleep. It was okay to sleep with Madoka watching over him.
