Disclaimer: I have not watched the so called season1, because I have been warned about the terrible plot twist beforehand. (which makes it a 2/10 drama from the get go)

This is basically a rather generic cdrama romcom. There is almost not a single new thing here, maybe with the exception of checking marriage license authenticity with amnesia. The chemistry is average, the comedy is average, the acting is average and the plot is average too (which means it's bad objectively speaking). There is also a rather typical semi-weak love triangle, though it ends very peacefully.

What makes this drama stand out a tiny bit from mediocrity is that it's a bit shorter than normal (12ep kdrama length) and so the plot is progressing rather quickly & there are no big annoyances anywhere. It's basically 70% fluff n sugar, which is something I always appreciate, even though the romances could not have been any shallower. While the villains are really poorly written and all, the fact that they barely have any screen time & fail to cause any big upheavals is pretty great.

One thing that somewhat annoyed me is that the drama has several very forceful kisses, but it's played off as successful seduction or something along those lines..
Oh I almost forgot, some of the product placements are just direct ad breaks basically, they start talking about certain brands directly & unnaturally. (Adolph Shampoo & whatever sanitary pads)
