   Summary

   “Hey Sakusa?” Osamu asked.

   “Hm?”

   “Why’s my brother think yer in love with me?”

   Sakusa choked on his tea.

   Motoya burst into a fit of laughter.

   Kita looked extremely confused.

   Suna sighed, “That's probably my fault.. but in my defense your brother is a dumbass.”

    

   ---OR---

    
   Suna tells Atsumu that him and Sakusa share the same taste in men and Atsumu now believes that his long time love interest is in love with his twin brother. Sexy chaos ensues.
