Subaru is at home doing his favorite thing, reading... but then Hiroto and Kawase show up, robbing him of his time alone. Then Kawase suddenly orders Subaru to buy a collar for Haru immediately, saying it'll help identify her in the event that she gets lost. So Subaru heads for the pet shop, where Nana helps him find a suitable collar. But Nana also tells him that many cats dislike collars and only end up stressed out by them. Will Haru approve of her new collar?
