    Can’t wait this drama since last year’s premise with Lee Young Ae stars in it. Almost 14 years since her last hit drama “Jewel in the Palace.” Why just out now?? Have been waiting for you. Her looks almost having no change compare to her in JITP. She’s true natural beauty.

    Also for SSH, can’t wait because his last three drama didn’t make that much. Hope this drama do well and make at least our or beyond our expectations because the premise seems promising.

    Lanie Says:

    Giving to this two popular leads, definitely this writer wanted this drama to be the top-hit but too bad, I’m not so interested in Korean histories.
    Lee Young Ae always given a role as mighty lady and I don’t agreed to it by judging 1 hit drama all times. She is really a crying dude and her acting is really like a mother figure to me. No thank you, I’m not going to watch it. It might be a very boring storylines.

    Simon K Says:

    Jewel in Palace is still one of the best Korean drama of all time. It is unfortunate that Lee Young Ae stop acting right after that. I am very excited to see her again, perhaps she will look very different after so many years. The story sounds interesting. Shin Saimdang must be very important to have her face printed on the money bill.

    keena99 Says:

    I don’t know if this drama has lost the “on air” timing or not because SBS don’t have that much hits this year. Not that much promotion itself. I hope this is wrong, because the story synopsis seems promising and no doubt for main cast of this drama. May this drama become a big success and big impact (positive) for many people.

  33. 33
    Odies Says:

    Is there anymore poster for this drama? Actually seems beautifull and simple, but at the same time feels lonely. Hope for another posteer contains of two or more main character in main poster. Otheer charaters seems still unclear enough. No doubt for Lee Young Ae’s star power.

    LuvK Says:

    2017, 1st interesting drama. At least we have good drama to watch and not have to try crap ones.
    But after Seung Hoon’s poor taste in girlfriend, not too keen to watch him really.

    success Says:

    “SAIMDANG, LIGHTS DIARY”…WOW…a drama I’ve been waiting for some time to air and finally the day is close! January 28th, perhaps? I am not familiar with Lee Young Ae’s acting, but according to the reads, I am very impressed and am looking forward to see this seasoned actress bring her expertise to the screen. A difficult role and a huge task she obviously accomplished along with the gorgeous Song Seung heon. I’m very familiar with SSH’s work as I’ve followed him since 2007. OUTSTANDING actor and I have no doubt in my mind that “SAIMDANG, LIGHTS DIARY” will skyrocket the ratings in an impressive way. Both actors will bring the Joseon Dynasty into our homes…what a delight and an education it will be for some; like myself! WONDERFUL!!! Thanks Lee Young Ae and Song Seung heon Honey for your hard work! Lovingly, I look forward to watching this spectacular drama coming our way real soon!!! KAMSAHAMNIDA!!! <3 <3 <3

    I watched LYA drama since 2003-2004 Jewel in the Palace it is interesting it became big hits. and i think this drama Saimdang Light’s Diary is interesting and become big hits too. LYA is outstanding actress in korea. and SSH i watched his dramas Autumn in my Heart,East of Eden,My Princess,Dr.Jin and When A Man Falls in Love. GOOD ACTOR AND GOOD ACTRESS PERFECT TO THIS DRAMA.
