Okay I finished it right now, let me recap. In the original, So Mi and So yeon were together, their father brought another woman to the house as mistress or whatever, their biological mother couldn't endure that so she committed suicide in the closet? or was dead long ago? If the first statement was true so yeon seeing her mother hung in the closet or a trace of hallucination, she pushed the closet to try to save her but ended up falling below the closet and due to injury and lack of oxygen she died. The mistress heard the sound and saw the scene but didn't try to help. In other hand, So Mi who was frustrated having her father a mistress , left the house in rage and didn't think to check on so yeon who was left behind and died. Everything happened after in the house was a creation of So Mi head who was literally hallucinating and deluding her sister presence, leading to her paranoid behaviors. Maybe also So yeon agonized spirit was giving a hand disturbing the mistress and haunting her Idk. Someone can guess if I understood right the movie who gives you goosebumps.
The idea of a season 2 is good but not without Han Yu Ri please. Her partnership with Cha Eun Kyung and their chemistry and bromance is what made the drama successful. I really root for their duo. Anyway Jang Na Ra on her own can make a drama go smoothly and pragmatically.
It's a very bingable series. I watched it in one sitting and enjoyed it for the most part. There was some ridiculousness,…
Yep the ridiculousness from my part, is the mafia team that execute other players overnight when everyone is dead-sleep (it's like they have been turnoff) for them not to feel anything being stabbed or strangled. Another part is that the drama was way bloody which not suitable for minors.
This drama was way very good as suspense, mystery and thriller and kind of horror and goosebumps until the last episode that comes and crushed everything. How obnoxious park se un parents and psycho they are to made these teenagers suffers like this. Okay they deserves discipline and punishments if they had bullied and neglected their daughter pushing her to commit suicide but it doesn't mean to go this far forcing them to play a live game fighting for survival and with a sense full of lies and betrayals. while manipulating their memories. You feel grieve and injustice for your daughter, go collect evidence and punish the responsible with the law not with unlawful methods like that. I am not saying those teenagers are good and angels Some of them are insupportable and creeps me out but they still minors and not mature enough with no upheld rationality for their behaviors. What frustrated me more is restarting the game in the end scene. This is unbearable. I am really disappointed by the ending. It would be perfect if had park se eun being alive and playing this game discreetly with them to get revenge and not a solo act of her demoralized parents especially the mother. My rating is for the first 11 episodes is 9.5/10 and for the last is 2/10. As overall an 8 would be acceptable. I got hooked till the end for nothing. As actors, I liked lee jae in performance she has a great talent. Kim woo seok and Choi Ye Bin did great too.
I actually dislike that about koreans. It's not like the Joseon dynasty. When someone make a sin it doesn't mean all his lineage and offsprings must suffer and be haunted by that from the publics
K-Drama 
such a complex language
But sometimes I hear in kdramas calling a medical doctor 박사님 as he is expert in his field althought the original name is 의사 as i recall
