   Summary

   Genya and Tanjirou have a nearly established thing, but it's not quite there as they grow closer during the training arc. They're interrupted during an intimate moment in the garden and Genya is on his way to take back what's his.

   Or

   Genya learns Zenitsu fucked Tanjirou. He doesn't like sharing.
