My reason for picking this drama to watch was simple - the leading man, Han Dong Jun. He's gorgeous. I watched him in 'Siege in Fog' and charmed I was. On the whole, I enjoyed this drama.

Thumbs-Up for:
- The leading man, but of course. He is tall, handsome, very deliciously charming.
- The FL is pretty cute.
- I like that ML and FL behave in a mature manner. Once they have decided to get together, they have (in general) open conversations and behave like mature and sensible adults. They understand that the other party is a unique individual and with personal goals to achieve. They support each other and do not get in each other's climb up the corporate ladder by being petty and silly. I truly like that they behave like two mature adults who love each other and want to make their relationship work out.
- The second FL is pretty cute too.
- I like that the motivations of different people are gradually explained as the show goes on and that hatchets are buried.
- I like the relationship between the 'sisters' - FL and second FL. I like that they genuinely love and care for the other party without interfering unnecessarily.
- Happy ending though fairly cliched.
- The OST is great. I like the jazzy feel and tunes.

Thumbs-Down:
- Watching the crazily obsessed boyfriend in the form of Xi Jia Bai was extremely painful. He appeared extremely neurotic and unhinged.
- The very self-absorbed senior/ tutor of the FL who came across as totally obnoxious and egoistic. He said things that were totally out of line and that were extremely old-fashioned and inappropriate.
- Taking credit for another person's work (but it's the unfortunate 'norm' in workplaces and in life).

Overall, my verdict:
Watch this, especially if you like a mature drama in which the FL and ML are both good-looking and are both committed to each other once they have formally confessed their genuine feelings to each other. The romance between the two feels real and they have chemistry. Their relationship is an 'urban romance' in which two people try their best to make their mark at work while juggling a romantic relationship.
