    Hyeongnam Says:

    If a young man and a beautiful young secretary were together almost every day for 9 years and never got it on, one of them is gay. The biological urge to procreate is more powerful than will-power or a chastity belt; what to speak of moral codes of conduct.

    iLy Says:

    I’ve watched this drama, and I found this one is interesting and I decide to follow this drama till the end. this drama has usual plot = the man is rich, woman is ordinary people, they suffer. but this drama still have an interesting part of it that make me want to keep watching it, like fresh comedy scene, awkward moment beetwen the leads, though I think assistant Bong’s character was too weird.

    I don’t feel the chaebol (rich man) aura on Park Seo Joon at all, but that wasn’t a big deal for me. I still can enjoy the drama. I surprised with Park Min Young, how she can perfectly act as secretary, how that role really suit her.

    Indeed, a very good drama! BRAVO for all the team!
    Regarding the two main leaders, they have 200% compatibility. Park Min Young and Park Seo Joon are a stunning pair. Park Min Young is an amazing Lady, I admire her! When I see each episode I have the same emotions like when I saw Love in the Moonlight, The descendants of the sun, Moon embraces the sun etc.
    All the actors are perfect in their roles, and the younger ones are super cute. Well Done! CONGRATULATIONS!
