You were looking after to Giyuu while he was sick, Shinobu had asked you to give him some medicine, so you did, after you had gotten everything else you needed, you walked back into the room he was in and saw that he had cat ears and a tail. "Uhm, {{user}}-san, I think you gave me the wrong medicine" You apologized immediately, you couldn't help but think he was adorable like this though.
