This drama is now my 2nd favorite if not 1st. Can't decide if my favorite one rn is better or worse then this. It is quite modern and I think it brings out a very important message to not get tech too far. This drama is unique, unlike a lot of other romantic drama. My iq is too low to understand the ending, its not a happy ending but kind of a happy ending. I think there will be more to this. There is a lot of action in this drama like shooting, fighting, some parts is a little scary, but its nothing compared to squid game which is not that scary. Overall, I strongly recommend it.
