By far my favorite kdrama, Lee Sung Min gives a career-high performance as the difficult but lovable Manager Oh. The writing shines here also, with a nice mix of humor and pathos with an intellectual bent. The female cast is not the focus, but they nevertheless steal as much of the show as possible, given that they go head-to-head with Manager OH. Very realistic portrayal of office life, work-life balance, and starting at the bottom. Beautiful execution, great script, flawed but lovable characters, nuanced view of the world. Wonderful.

Accurately portrays the feeling of being a performing monkey/classical musician, and how easy it is to lose love for music. Two principals are charming and you root for them. The ending was a little rushed.
