This was fairly entertaining, it did not feel like time wasted. That said there were some cliche moments & some unnecessary plot developments. The second male lead definitely overstayed his welcome, the actor had the exact same character in I Can Hear Your Voice, but here he had a LOT more screen time.(I hate forced triangles) This feels like the same sub genre of romantic comedy that Secretary Kim & Oh My Venus belong to, but the writing is definitely inferior. For example I was anticipating the moment of Rui returning to work after his identity is known to everyone, but they completely messed up the timing with the "OH noez Bok Nam is dead, let's separate for life" plotline , so the comedy of that anticipated moment was completely destroyed for no conceivable reason what so ever. The ending is a bit of a mess too, it is supposed to be one of those 3 hour long happy endings, where everyone is getting the happiness they deserve, but then the focus has shifted to some side characters that I did not much care about and even for them I was like WHAAAT is happening at times, like how Mari's story ended on a sour note, or how that SooBin cameo has turned out.

I listed many negatives, none the less this is still a great show. There were about 4-5 truly outstanding episodes & they did not drag out the stupid shit too much. I'm also surprised how I did not figure out the obvious meaning of Kobashi, I was embarrassed about my mind being blown in that big reveal scene at end, which was a pretty great way to end the show too.
Kim Byung Chul surprised me, at first I couldn't even recognize him being the same actor that played the main villain in Goblin. Such a great supporting actor! I'm suspecting that the gene that makes certain Koreans look like rock fishes, or blow fishes help them with acting somehow.
