>>3078699Rahc was already shown to be happy to assist when darling asked for her help in the beach chapter. As I said, these people are not out to be as much of a dick as they can, its just that if you want their support you'll have to ask for it.
It's not necessarily a bad thing, unless you're a neurotic that thinks other people should be able to read their thoughts, but it's what leads me to believe rach isn't the kind of girl that would secretely do the chores just for the sake of being nice. I think you need to look the way of manako or tio for that.
