   Summary

   Iwaizumi Hajime has been pining for as long as he can remember. Oikawa Toru has been hoping that Iwaizumi would notice him for as long as he can remember. One night, in a luxury hotel room right after Argentina beats Japan, they get the one thing that could make this predicament worse: each other.

   Inspired by the relationship in Heated Rivalry. Also, hot gay sex.

   (The smut is skippable, technically. It begins in chapter 2.)
