I have a high expectation with this series since this was created by Korean producer, but this series let me down so bad. I am still glad to watch it as I discover how great Choi Jae Hyun is. I hope he get many projects after this.

Let me break down my review, beware it's long:

[STORY]
While the plot seems unique for BL, the love between supernatural being and mortal is nothing new and has been adapted in many movies and dramas. The supernatural elements in this series was not well executed and there were many glaring plot holes that made me lose focus on the story line. The ghost element was only used as plot device but the screenwriter was too lazy to construct the characterisation of the ghost itself. While fantasy drama did have more freedom for illogical things to happen, a set of boundaries and rules should be established in the realm to guide the viewers about the said fantasy element. And this series simply doesn't a give a shit about this and expect the viewers to accept many questionable things happen and pretend that was okay.

The most annoying plot holes here was no clear concept on how the ghost element implemented in real world. How is it possible that no one bat an eye with all the ghosts' shenanigans? Anyone should freak out when utensils float in the air or luge drive by itself, yet no bystander say a word about it. Peach was not even subtle when talking and showing PDA with Yoon Oh, yet no one questioned his sanity. It seems humans have well adjusted to cohabit together with ghost lol. This series never explained how the ghost's world works. the ghost literally can use and touch any solid object, like use utensils for eating, change clothes, keep the key, use facial mask for better skin, ride a luge. the ghost behave exactly like human and we are supposed to just take it in without any explanation. and if they don't have any problem to use and touch solid objects, they should be able to touch and communicate with other human, but nah

It was also not clear how the ghost cease to exist. Mario said that ghosts should resolve their sorrow before the 49th day so they can go to the other side and not become evil spirit. Yet Mario has been exist for 20+ years and neither Peach nor Yoon Oh question this anomaly ever lmao. Even after Mario found his peace, he was still around. Like how?? Why he can't go to the other side?

Finally, what's with that ending? At last, I am content that Yoon Oh can go to the better place. It is happy ending in my book, everyone getting their own peace and amend. But suddenly they have to ruin it by making it vague that Yoon Oh might be back. Like, what's the point? I thought I won't be disappointed in the last ep, and yet here we are.

[ACTING]
Yoon Oh and his mom are hand down the best part of this series. Their acting is so good and I like how their eyes can convey deep emotion as well. I feel like their talents kinda wasted here as I found the story a mess. I would rate 10.0 for them, but unfortunately Jimmy's acting was like a sore thumb. His acting was awkward and since he is the main character, it kinda ruined the moment.

[MUSIC]
The song choices are good but not really memorable.

[REWATCH VALUE]
This series managed to peeve me every episodes, so nope. I might rewatch YO's cuts only to appreciate his acting.

[OVERALL]
Might be enjoyable if u don't really care about the details. This series was beautiful if it was watched scene by scene, but there were just too many plot holes too ignore and the ending pissed me off.
