This is one of those drama that gives you a roller coaster ride of emotion from laughing, to being scared, to being sad, to being mad and to feeling in love.

The plot is masterfully created by making a one big storyline going in the background incorporated with mini stories you can look forward every episode. It keeps the hype going maybe except from the fact that the mini stories overpowered the main mystery. It was going good until the last few episodes which really fell flat for me although overall I still really love this drama.

As for the casts, I can still remember having a second lead syndrome when I first watched this on 2015. Seo InGuk is just so damn cute. During this second time I watched it, I realized how Gong HyoJin and So JiSub really has a good chemistry on screen. I'm a big fan of the dramas they starred on together and always loved how great they always deliver. Gong Hyo Jin being possessed GongSil is one of the most memorable scenes I can always remember.

The other casts also played really well making the story more flavorful. The ghost stories every episode is almost realistic that I actually thought that ghosts maybe are not really that scary. They just really have some unfinished business down here.

The soundtrack used here is one of the best soundtrack I've ever remembered in the K-Drama world. It matches the drama very well and most of all it retains on my mind.

Overall, this drama is still one of the classics in the K-Drama world and I still regard with high quality and high probability of re-watching.
