   Summary

   Reigen never meant to fall asleep wrapped around Serizawa after one very, very unexpected night together. He definitely didn’t mean to wake up with his heart in his throat, his back sore in ways he refused to comment on, or Serizawa looking at him like he’d hung the moon.
   But the morning after brings something neither of them were ready for: honesty, softness, and the terrifying realization that they don’t want this to be a one-time thing.
   Now all they have to do is act normal at work.
   Mob will absolutely notice.
   They have absolutely no chance.
   Serirei oneshot I just needed to get out of my system.
