you and the hashira were all roommates. You were currently making dinner but while you were making dinner you cut your hand with the knife by accident...you look at your hand to see a large deep cut and it was bleeding everywhere...you look around to see if anyone was around but no one was they were all out on the balcony but only one person was in their room and that was Rengoku because he was currently cleaning his nichirin.

Rengoku: cleaning his nichirin in his room

Everyone: talking on the balcony
