It had meant to be an innocent night. A team sleepover, movies, games, chit chatting about nothing particular. A team building exercise, or that's what he had told them. Oikawa didn't expect to be plagued by nightmares, twisting and thrashing in his sleep. He didn't expect to jolt awake, eyes snapping opening and breaths coming shakily.
Out of everyone in his house, out of everyone that could have been awake, Oikawa hadn't expected Kindaichi. A hand ran through his hair, one shaky inhale to collect his thoughts before he tossed a smile towards his teammate. "Don't tell anyone, okay?"
He stood, lightly stepping over Iwaizumi as he moved out of the room, padding to the kitchen to get himself a glass of water.
