Then probably you must have not watched this drama yet, n came to know people's review before watching it, Well i did the same thing. Reviews helped me to go ahead n watch. So even i felt i should tell my point of view. Go ahead, watch this drama.. It's really nice one. There is lot to learn in this drama, how they survive on island for 4 months and how they escaped, how few died. Till their escape from island i found thirlling, but later on choi tae he feels in epi 13 that why he is doing all this, why he is living this kind of life. Despite of having this feeling, he still tries to kill jooh oh. What i felt it, if he admitted himself he was wrong then, there would have been happy ending. Moral would be like how much ever you try to hide the lie, you can never rest in peace till you don't let the world know you were wrong.
