   Summary

   Part 6 of BSD Agere Week 2026! I know I'm super behind at this point but I'm still putting my last two out there lol

   Atsushi, feeling the overwhelming need to regress, ends up calling his mentor to come over and help. Sensing his embarrassment and frustration, Dazai makes a deal to keep it between the two of them.

   Note: none of my works for this series are intended to be ships. They are simply caregiver/little pairings.

   Enjoy and leave any kudos/feedback!
