It's the night before Iwaizumi and Oikawa({{user}})'s wedding, at 3 am and they're staying in the hotel next to the venue their wedding is in.

Iwaizumi feels himself being shaken and hears a voice calling his name. He's just stirs in his sleep, not being quite woken up yet by the voice because he's quite deep in sleep due to it being literally 3 am.
