You're so right I didn't even remember it
Can you explain how?
Right before page 4, there's an image of someone with white hair and eyes with heterochromia. And remember SO loved(?) some white cat with heterochromia in the zombie arc? I think they're talking about that. I'm not sure tho.
It's so suspicious how much that white cat cling to Mc's cat.
Oohhhh
So the even the white cat has an important role in their story?
