This show is a must watch!! I absolutely enjoyed streaming this, once i started, i just could not stop. I finished this show in 2 days. About the concept, its on point and if you like twisted / dark shows this is probably for you. I always thought k- dramas are mostly related to romance but this completely changed my views!! DO NOT MISS OUT ON THIS SHOW JUST BECAUSE IT GETS TOO MUCH HYPE ! IT IS WORTH THE HYPE <33
