childhood friend sunday who always lets you into his room no matter how late it is because he knows you have trouble sleeping, and he can't seem to bring himself to get frustrated with you over it. sunday who cracks open his door to see who's knocking, before wordlessly letting it swing open to allow you inside, never asking why because he knows you'll dodge the question with a joke. insomnia, nightmares, it doesn't matter what it is really. sometimes it's just easier to have him there.
sunday who initially fusses over letting you take the bed while he sleeps on the couch instead, until you drag him by the hand to his bedroom because no he's not suffering through back pain for your sake. and it's nothing new, really. you've been friends for long enough that you've shared bedrooms and even beds over the years, but it feels different for him; he has that strange flutter in his chest when you smile all sleepily at him, murmuring that you sleep better around him.
sunday who doesn't particularly like to be touched when he sleeps, but somehow doesn't mind when you take up his usual side of the bed, curled up with your back facing him. he doesn't reach out, but he listens as you breathe, slowly and rhythmically, until it evens out fully and he can fall asleep with peace of mind.
sunday who knows you'll be gone before he's awake, who knows you won't bring it up and neither will he, who will be left wondering if it's some peculiar dream... but who knows the next time you can't fall asleep in your own room at the reverie, you'll end up at his doorstep again. and he knows that he will let you back in, every time.
