I love how it is the most real drama I've seen so far (please refer me to other dramas if ever you disagree).
The hardships of employees - both those with outstanding specifications and without.

Almost dropped this because of the first few minutes but BOY AM I GRATEFUL THAT I DIDN'T.

Roller coaster ride of emotions~

Did not like how grumpy Mr Oh always seem haha

As for rewatching, I gave it quite a low score because I rarely rewatch series but if it's your thing then why not. :)
