Fluff: Harry insisting that he makes you something to eat (French toast or an omelette) when you're staying the night as his even though it's 2 am because he here's your tummy growling while trying to sleep
“Harry oh my god it’s fine, please.”
“You’re hungry. M'not letting you go hungry on my watch.”
“Just come cuddle me and sleep. I’ll eat tomorrow morning.”
“Nuh-uh. Let me at least get you a glass of milk or something.”
And when he comes back five minutes later, he has milk and toast because, “You’re gonna eat, bug. Y'have to. I don’t want your tummy keepin’ me up.” With a smirk and a kiss to your head.
