  3. 3 : hotmail login english Says:

    I see Ji Sung I click. One of my favorite Korean actor. Lee Se Young is cute, too.

  4. 4 : Fado Revere Says:

    First episode is good. Focusing on female who lost confidence in herself as an anaesthesiologist and the prison inmate that helps her regain it, appears to be the plot at the start.

  5. 5 : Fado Revere Says:

    Episode 2 is even better. The drama moves out of a dreary penitentiary into a modern hospital. A connection between the female doctor and the now former inmate is established.

  6. 6 : MaxT Says:

    This drama is even better than Doctor Detective. Don’t miss out!

  7. 7 : nadhira amalia (@dhyeraa) Says:

    i so happy that his back again but i wish see ji sung in romance comedy drama i love his act in kill me heal me and this new drama is cool and good too 🙂

  12. 12 : Peanuts Says:

    Love this drama though everytime when I watch it, it brings back painful memories for me for the next few days after that. And just when I’ve recovered, the bad memories would return when I could not helped but watch the continuing episodes again. Repeating the torture for myself.

    When watching this drama I can relate to how Si-Young and Yo Han feel when faced with heartbreaking and desperate situations in their jobs and at times when helpless set in.

    My patients were not people, but were dogs. But the situations and feelings were no different from what Si-Young Yo-Han’s. My patuents were very sick and dying homeless dogs. I was a volunteer at an animal shelter. My opinion was to put them to sleep permanently in order to stop their sufferings, but my seniors wud not believe in doing so. Their decision only prolonged the dogs’ sufferings. It was heartbreaking.

    Eventually, I had to stop the volunteer work when poor health forced me to give up.

  13. 13 : aries_nim Says:

    12 episodes of this drama so far and everything was great. The plot is getting exciting and there’s a lot of secret to be revealed. The acting, plot twist (not really plot twist oh gosh idk how to explain it😂) and a little hint of romance makes me feel very excited for the next episode. Watching this drama while it is still ongoing makes me crazy 😭😭😭

  14. 14 : Carmen Says:

    The most I love from this drama is the songs and music they are using really good omg

  15. 15 : Jukbang Says:

    Will Dr Cha die at the end?
    Love Dr Cha and Kang Shi Young moments!!

  19. 19 : Diana Says:

    It’s different and I like that. Very interesting and informative.

    Lee Se Young is cute but her eye expressions are all ways the same. Her eyes show no emotions. Distant and far away.

    Ji Sung always does a good acting job whatever role he is playing!

  20. 20 : Su Says:

    Daesang FOR Ji Sung this year…!!!!!

  21. 21 : Lobbyist Says:

    Good drama

  22. 22 : Kmc Says:

    I like the drama but why they put hair extensions so horrible on Kang ship young. Just have her short hair would look better. It looks funny on ponytail or when she have her hair down

  23. 23 : Mina_L Says:

    I wanna say it again …worth watching it! …. so sad these drama will be end this week….

  24. 24 : Misu Tira Says:

    Awesome drama with amazing actors, actresses and the whole crews. Thank you so much for the awesome drama….

  25. 25 : MaxT Says:

    This is the best medical drama to date. I can watch it over and over without getting bored. Highly recommended. 10/10

  26. 26 : USA Says:

    This is truly a disgusting storyline, justifying early dead because of pain. Lacking character in humanity, no endurance, and looking for a way out. This writer discredits & minimizes all those Korean ancestors who suffered through the war, Japanese occupation etc. Those Koreans lived & loved with resolve determined to survive for them, their family. Life is always hard, and this sicka** drama is a lowest of low in human story telling.

  27. 27 : Nishakool-yung Says:

    Thanks all to produce the feel good series like this. Love it love every scenery 😘😘

  28. 28 : MaxT Says:

    Best OST in 2019.


  29. 29 : A Caretaker Says:

    USA Says…”justifying early dead because of pain”…”no endurance”. Remember those words if/when you develop a debilitating disease that brings you so much pain it becomes intolerable and all you can do is cry and scream.,,day, after day, after day, after day. THAT’S NOT LIVING! BTW…Karma’s a bitch. And why in the world are you making it a “Korean” thing??? Koreans are the only ones who have pain? Koreans are the only ones who contemplate euthanasia? It is your ignorance and comment that is sicka***,

  30. 30 : malar Says:
