   Summary

   Kaigaku has always been an asshole. Constantly smoking, drinking, and staying out late, even when Jigoro gave him a proper lashing. Zenitsu loves his adopted brother, but god dammit does he wish Gramps would just throw the dumb bastard out of the house. Though he would never say that to anyone out loud.
   ___

   Zenitsu and Tanjiro plan to spend the weekend together. Kaigaku prepares Zenitsu for what to expect.
