If you watch korean drama, My Name is an adjacent drama to this serial. However there are differences but you can say these two dramas are like long lost siblings.
The plot is so good. I am the type who should find the first episode interesting to continue a serial and I CONTINUED. the casting is a top tier here by choosing fern and peach (and their chemistry is VERY GOOD here i swear to god. never doubt their acting btw). This drama realistically illustrate that human can do anything. Human being inhumane in things they are greedy in, and the value is ; do the opposite of what these evil do! It's that simple. It opens our eyes to be more aware of what happen. And one last time, i really recommend this to anyone who love thriller revenge series.
