The drama is a mixture of a lot of things....while this may be a good thing when executed well but here it wasn't.
They just tried to include everything from elementary schools and female jealousies to secret kids and brothels. Honestly I feel like they just tried to put in too much in one place.....also there were quite a few ends that were not tied properly and like if you've stretched the damn drama till 16 episodes might as well give a better happier ending.....
It did give off sky castle and penthouse to me with the writing and execution but maybe it's just me...
Overall I would say it was good enough for a one time watch...they could have made it better and shorter had they reduced a couple elements.....
Nevertheless a good one time watch
