My 4 categories are Acting/Cast, Writing, Direction/SFX/Music, Entertainment Value.

I really had high hopes for this one. I love Rowoon (로운); I think he's a great actor. I saw some short clips of this drama that highlighted his portrayal of a quirky character in an unfortunate but comical situation. It seemed very charming. So despite my dislike for the female lead, I decided to give this drama a shot...

Acting/Cast: This is going to sound so harsh...honestly, the only positive in this category is Rowoon (로운), the male lead...and even he struggled. I don't know if it's his fault or the writing or the direction or all of the above, but he couldn't hold the character. It was such a unique character, too, with an extremely distinct personality and it just...fizzled away as the drama progressed. I would catch glimpses of his former self here and there but it only served as a depressing reminder of what once was. Jo Ba Ah (조보아), who played the female lead, wasn't any better. I had really disliked her after watching her ruin Tale of the Nine-Tailed with her horrible acting. At least she had improved in this drama. I was surprised that she wasn't the reason this drama failed. The villains - all three of them - are lame. The side characters tried so hard to be likeable and they just couldn't pull it off. Oh, I almost forgot about that poor 2nd male lead... a K-drama pet peeve of mine -- disrespected 2nd male leads. 1/10

Writing: I'm so sick of the "we loved each other in a past life" trope. It's so over done. It's seriously becoming another huge K-drama pet peeve of mine. The writing and plot started out strong. It was an interesting premise with a dark, ominous undertone. Unfortunately, this all goes away pretty early on in the drama and it just becomes a boring, typical romance...with a stalker cliche. I think it fizzles out around episode 8 or 9. Ugh...the beginning was so good...I'm so disappointed... 4/10

Direction/SFX/Music: This drama does have good cinematography and production quality. This is definitely the strongest category. The OST is decent. Direction though, I did not agree with. Going from unique, quirky, cute, with some creepy and even adult vibes to a cookie-cutter romance. I forgot the ending. It's only been a few days and I already forgot. That's how unimpressed I was. 6/10

Entertainment Value: Getting through the 1st episode wasn't quick for me. I don't know if it was the drama or me. However, after the 1st episode, I really got into the story. I was excited to watch it. I really loved the male lead's character and the dynamic between the 2 leads. I thought the plot itself was very engaging. Then, I reached the 2nd half of the drama and as I continued watching to the end, I experienced all the hope within me slowly shrivel up and die. 4/10

Now I'm sad.
Overall, I gave this drama a 4/10 due to the complete disregard for the solid foundation that had been established in the beginning of the drama.
