I know he probably said "Hai?" in the last panel, but that doesn't always literally mean "yes". In this case is was a "What?" As in "What did you say?"
BTW cats aren't supposed to drink cow's milk because they can't digest it properly. Sure they might like that, but it might make their tummy hurt, so watch out!
also, most black cats are male!!! I freaking hate how every manga/anime with a cat-turn-human, it's always a female black cat!!! I freaking hate this trope by now
they aren't rare, but it's like 70/30, so for literally every single manga/anime to have black cats turn into human female is dumb (not counting the black cats in BL who turn into male, because well, those are Boy Love's stories)
I'm genuinely asking you to find me a not-BL story where the cat-turn-human is a male black cat.
