Wait... how can anyone tell she's human if she (the pink haired friend) became a goblin? I thought that was the whole point, because she was not a goblin bride when they healed her she became fully goblin and that's why she doesn't remember her time as a human? She even says she wants to hear stories "of when I was a human," meaning she's not one now sooo...?
Also that crush the friend's got is gonna end in heartbreak or betrayal, maybe both.
