i think its RorAsa who are the mothers bcoz asa always takes care of her members and rora bakes cakes and sweets for them and she is a great unnie for chiquita
In my opinion rora is the closest with Chiquita and is often seen taking care of her, not anyone else. While asa and ruka take care of everyone. No hate to rora though. Also is it only me who feels that ahyeon and rora are not very close?? I could be wrong thou.
all of them are close,just not much videos of them interacting though i think thw company push ahyeonchiquita tandem❤no hate though,,love all of them...
