One funny thing I found out almost at the end of the series was the female lead's name Woo Joo means "Universe" in Korean. Kind of unique girl name.

Not really a review here. Just pieces of my perception about the drama.

Almost didn't recognize Jung So-min here. She became more mature in appearance and in acting here rather than the cute-girly-funny roles in the past. Good with long hair, ponytails so cute, too! Clothes? Few and simple but very chic!

Jung So-min acted in switching mood effortlessly and convincingly in playing an insecure, unstable, psychotic, easy to explode while still a pure warm-at-heart-craving-for-love girl. It was no easy task and she nailed it.

And also so good to see Shin Ha Kyun back to wear the doctor white coat since the 2011 medical "Brain" drama.
I saw the interview that Shin was joking that with this kind of doctor role he didn't have to remember so many medical terms like in Brain's and definitely no neuron operating at all.

Shin Ha Kyun is not your typical good looking male lead but oh boy he can act.

Long time ago Shin had a Boundary case like So-min's but his patient committed suicide by jumping to the ocean when they were on a cruise boat.
It left him a PTSD. His admirer female friend doctor (Park Ye Jin) believed he had to stand up where he fell. So she arranged for him to treat So-min as her psychologist. OK, here we go!

Shin/So-Min didn't have the hate/love as usual, just a stranger-to-like type of sort, on the fact that they both have similar scarred soul.
- So-min still resentful of her adoptive mother who adopted her at 6 then returned her to the orphanage when she was 12 and of her biological mother that gave her up to the orphanage.
- Shin has a trauma past and an Alzheimer's father as his burden.
(Does kdrama had to absolutely put in the cancer and/or amnesia/Alzheimer's factor in every series? - Come on, I've about to had it)

I think this drama definitely was not designed for younger audience crowd who searching for hot boys/girls. All the actors here was middle-aged.

Beside Shin and So-min, the other actor roles was very blurred and fainted. Park Ye Yin as Shin's admirer female friend doctor role was weak, mostly sitting and listening to everybody complains.

Tae In Ho also in support role was no better, not really a villain or Shin's rival. He was there with kind of dealing with his own love and life issues and did not distribute much to the story other than filling the empty times.

The So-min's side was better, her restaurant boss friend (Joo Min Kyung) has much less screen time but more brightly shine as supporting/enduring her mood swings and in the mean time found her cute love story.

Back to the main leads, there was so many funny cute little scenes I enjoyed immensely.
Like So-min forced Shin to sing to the flower on the reason the flower needs to hear a man's voice. That way they can "raise" the flower together...
Shin: But, but I can't sing...
So-min: Do you think the flower care about that?

(Funny? Hey, what else did you expected from a psychotic girl?)

Or where she showed off to the unnoticed doctors the bracelet Shin gave her the other night, she blurted out when still no body paid any attention: "You doctors really are clueless", everybody looked at her and her restaurant boss friend had to pull her off the seat towards the kitchen.

How about when she declared an abruptly end of their love story in a amicable way, sorry-I-was-mistaken-my-feeling Now-I-realized-that-I-am-not-really-love-you-thank-you-about-everything. She tapped lightly on his shoulder then left.

You can see that Shin like took a punch right on his face. He petrified for 10 seconds and suddenly dash off his office to chase her to only find out that she stood there right smiling at the door when he opened it.

Bam! She finally got her revenge right there - After he rejected her feelings multiple times. Mr doctor, you know the felling now?

(Well, some more spoilers?) Then they went to the park, and when Shin accidentally confessed his love to her there, So-min acted surprised then suddenly kissed him on the cheek and immediately defensed herself: "It wasn't me! It was my lips! They suddenly did it. You know I was not in my right mind"
Shin cannot doing anything else rather than nodding to accept her defense, then she punched him repeatedly (lightly) to the chest: "Why you are nodding? Omg, You're too much" then she ran away... Oh, girl!

While Shim served her instant noodle, So-min was blabbing in listing the reasons she loved him: "Also, you're a great cook" - Shin: "Well, it wasn't that hard, just throw it to the boil water". By the look of her face, Shin learned his lesson: "Don't argue with a lunatic girl while she listing the reasons why she loving you".

On a side note:
I absolutely find no trouble at all on the so-called doctor/patient relationship that several peoples screaming here.
Define me a doctor/patient relationship. If you go to a doctor for a regular common cold, then you are now a patient, means you cannot date that doctor?
How about Foot doctor? Eyes doctor? Dentist? The nurse that care for you when you stay in hostpital beds?
Where you are going to draw the line? Or pick and chose this case was OK and that case was not?
If you are no longer a patient then how long the statue expired before you can see him/her for a date?

Pick a similar one - Teacher/student relationship...
You cannot date your math teacher in your college? How about you went to a dance class after work then date the teacher there? What was the different?
Still a teacher/student relationship? Where are you drawing the line?
Boss/employee? Employee/customer? Old male/young female?
Old female/young male?

To me all this ethical was nonsense BS, DS - As long as they are over 18 years old and not violating any laws, they can date the hell anyone they see fit.
Sorry - End ranting.
