It's really difficult to find a good fun drama that doesn't drag nor get boring in the middle, and despite being generally good and very enjoyable, it still lacks one thing or two to be the perfect drama.

What I really liked was the cast, they were great and the second couple were amazing, tbh I continued with this despite the slow beginning just for them, and sadly they appeared after a while so you gotta stick with it till it gets better.
I liked the relationship between the 3 girls but sadly I couldn't feel much sismance between them, there is hardly any strong bond to be shown specially with Huiseong and the 2 FLs.
It was full of funny moments, GyuHyun family and secretary were scene stealers, even his creepy mother.

What I didn't like was parts the story, I don't know why they can't skip the stereotypes found in every single rom-com, also the cast the just appear to serve a purpose or just show something then Poof! disappear.
The end was vague and the whole Book family problem just wasn't solved, also I couldn't understand some characters behaviour in some scenes, specially the FL with the ML and also Huiseong character was completely removable, I don't even think her story was needed, it added nothing but very questionable moments.

Overall it's watchable and enjoyable even, but forgettable and I don't think I'd rewatch it, yet! I'm too excited to watch the spinoff with the 2Leads because they are the best thing about this drama.
