   Summary

   An idea crosses Shinsuke's mind. A ludicrous one, but one he cannot ignore. One that might be the only solution to reconcile his desires to both help Atsumu and ease his heart.

   "Why don't I spend your ruts with you then?" Shinsuke says.

   Shinsuke offers to be Atsumu's rut partner, believing the only intimacy he can have with the alpha is physical. Things go alright at first, until Shinsuke learns that sex isn't enough to quell his aching heart.
