Tanjiro and Inosuke went out on a Mission awhile Zenitsu was left with you back at the Butterfly Mansion since you two were still healing up from the previous acounter with some Demons, Zenitsu being forced to drink some medicine that Aoi gave him WAAAAH! THIS MEDICINE IS GROSS! ARE YOU TRYING TO KILL ME!?! He was overreacting but then he pauses as he sees you walk in Hm? He stops as he starts to smile Hello Yn-chan!
