If you are looking for just a cute enemies to lovers kinda romcom, this show is nice. But i would say that the show dont create much suspense as i thought it would and there's not much drama going on. Some problems aren't even solved and the writer just leave it as a mystery. At times, the story wasn't aligned. Sometimes, it don't make sense. Even the order of the lines that was originally sounds interesting, was cut off by another line, making the scene sounds so boring and old fashioned.
The only part that is best in this show is that the cute scenes of all the couples. But i wouldn't say that the characters are charming. The role of Lee Sungkyung as Oh Hanbyeol shows that she's a capable worker but other than that, there's not much of it. The writer only highlight her as a great worker but not as a charming women.
The role of Kim Youngdae was fine to me and kinda typical but acceptable. Some people may critic his acting but i would say it was fine. Since it's a romcom, his reaction that aligned with his acting make sense to me.
Overall, i would say that there are a lot of points in this drama that should be added and improved. If someone ask me if i would recommend this show, i would say no.
Sorry writers and directors but this is my opinion and as an avid kdrama fan, to me this is the only logical explanation.
