This was pretty much ➡️ AMAZING!

Great chemistry between both leads and the storyline has a development (this is almost impossible to find in almost any drama nowadays, everything is too repetitive and dull now).
The storyline goes back and forth between the past (from her POV) to the present. It centers mainly in the romance, the fantasy theme such us, helping ghost cross to the other side by letting go of their grudges, the mystery of the past story with her past lover and the also death (as she wants to die but she can't).
The characters are well constructed, my favourite is her (IU's character) her sassy personality and her toughness are different and difficult to see in korean women.
The male character is well made too with personal development/growth, his experiences teach him something that will make better in each episode.
The supporting cast was easily enjoyable too with the funny touch, I really loved their addition to the drama too.
The OST were beautiful and easy to the ears, just like the drama.
I really enjoyed watching this drama from the beginning till the end. I highly recommend it, you'll not regret and have a great time watching it.
RATE 9.5/10
