Although healer isn’t set in the blue house, in both dramas there is a big Powerful secret organization that basically runs everything that needs to be takin down....

i found this dramas very similar although graceful family was quite better. they are both about very rich families, conspiracies, being untouchable, cult like groups, daughter in the family exiled or treated unfairly, daughter meeting a helper/guy that becomes a support system. AND most of all the villans, both dramas have the kind of villan you hate to love or love to hate. they were very good at being evil but somehow they got my sympathy. in both dramas the villlan had an unexplainable fondness with the male lead. graceful family is better because the leads have better chemistry and there was no forced/cringe romance like in the k2.
