I've had my doubts when checking out the cast - it sure looked like an office romance to me, but man, I was wrong.
This is not romance nor is it a mere office soap. It's about people working in an office and the moments they share with each other. You got each office type you'd meet in real life portrayed as realistitc as possible for a drama series. You get to know each person's flaws even and yet you never end up fully hating on anyone. Every person has a believable storyline, motives, motivations.
On a sidenote, I'm an offive employee as well. Most of Misaeng is what my life is about - the work, the colleagues, the problems and epically funny moments, the bullying, the psychos, the coffee breaks... Wish I was as ambitious as Jang Gu-Rae, but mostly I enjoyed his naivety when facing problems and his loyalty towards Oh Sang-Shik and his colleagues.
My favourite characters would be Oh Sang-Shik, Kang Hae-Joon and Han Seok-Yool. I remember my first job as an intern and that first boss. The only boss so far I've ever actually looked up to (well, before that I'd worked at schools which was a completely different experience anyhow). Oh Sang-Shik reminded me of my boss, the only boss I've ever met that was absolutely loyal and who everyone was loyal to because of that. I've learnt alot from him and will always be grateful. Manager Kang, oh well, not gonna lie, I have a weakness for people like that and I loved his taste in women - I think this is the manager I'd definitely learn the most from.
While on the other hand, Seok-Yool, that one co-worker you really need in an office, who has more empathy than anyone else, yet sometimes seems like a dork. He's that good soul that'll keep the group together no matter what.
I don't really want to go to work tomorrow, it's a heck load of work and people are sick these days, so it's more work for those who aren't on sick leave - but I feel motivated after finishing Misaeng.
10/10 would recommend because Misaeng has that spark - that charisma that so many k-dramas are missing.
