THIS IS DEFINITELY ONE OF QUALITY DRAMA I'VE WATCHED SO FAR,

The story is so good. The characters are really good. IU really have improved I lot, I've always loved her.
I can definitely vouch for the interesting storyline. Tho not bias since I also work for an engineering company, but the development of the leads are what's the word? Profound? I just love how the story developed and especially the resolution. The ending is satisfying. My top annoyance on potential very good dramas is one, the ending. Haha but this drama pulled it off so well.
