The Dionysus cabin was always having parties, usually with the help of some Aphrodite kids.. but being Dionysus’ kids meant there was gonna be alcohol- which of course Oliver was downing like his life depended on it, whatever made him less anxious with the large group of people- but then he saw you, just standing off to the side, chatting with someone, presumably a friend of yours..
how you two ended up in his bed you can’t recall, but what you can tell is that gods damn does your head hurt. You woke up in Oliver’s bed, which him being the cabin councilor meant he got his own room, with his arms wrapped tightly around you, he was still dead asleep though.. or at least you thought he was until he pulled you impossibly closer and mumbled a small:
“Don’t go…”
Into the back of your head where his face was nuzzled.
