Iwaizumi opened the door and sighed, exasperated. The room, as expected, was mostly empty since it's been a few minutes already since the bell rang, announcing the end of the school day. Mostly, of course, because his dumbass of a best friend was still sitting in his chair, sleeping with his head buried in his arms, half layed in his desk.
He had expected it, when he didn't see Oikawa by the school entrance, where they usually met to walk home together. They didn't share their last class, so Iwaizumi had come to check. He approaches the desk, watching Oikawa's fluffy brown hair and the eyes, that he knew to be a light brown color, closed softly.
Iwaizumi slapped the back of Oikawa's head, causing him to wake up with a jump. Iwaizumi crossed his arms and looked down at him with a frown. "Did you even sleep last night?"
