   Summary

   In their shared apartment, Kokichi tries on Shuichi’s clothes—and a new role—by staging an over-dramatic noir detective bit.
   Shuichi indulges him with fond teasing, steady affection, and the quiet reassurance that some things are allowed to become a “him thing.”

   Post-canon fluff with humor, trust, and a very unserious detective.
