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. :)
