It's not spectacular, it's not gonna make your heart stop, okay sometimes yes, but it made me curious. It's this plot, those characters...
First episodes were half half. The atmosphere was heavy, that house, I hate that house and decoration, it added suffocation and on top of that, without being a ghost even her dad freaked me out. But Gu San Yeong and that ghost, what with the hair accessory, and why and why, and there I was calmly addicted to the story.

Gu San Yeong Was not the hero type. But I loved her.
She represents everyone who wish to stand for the right things but could weaken a little whan facing dilemmas, so was HongSae.
After HongSae really had more time screen and understood what really was going on, things got really interesting on a superior level. His encounters with the ghost were always strangely a pleasure to watch, he was the first one miss ghost talked to "normally". And My romance watcher self showed up liking how he cared for San Yeong, subtle romance is so realistic and touching.
Professor Yeom was interesting to guide the plot but maybe lacked a little thing for me to be fully invested in the character, his relationship with Ujin should have maybe lasted more cause it gave him more background and dimension.
Are ghost more frightening than humans,sadly no. A ghost is the symbol of human hidden bad desires. I liked how the writer took care of this side till the end.

A special mention to Kim Tae Ri's incredible interpretation of the ghost, she mastered it. And Oh Jung Se's too, I recognised some expressions of Sang Tae, fear, doubt, from It's okay to not be okay, rare are actors who acts that good in DramaLand.

PS: Can't the main leads be casted again together, pleaaase hh
