Reviews I read said this series is up there with CLOY and others as the best Korean dramas of all time. Sigh.
There is nothing best about this. At the end of the day, it is an average show with some average acting and a really not-that-believable storyline. There is sweetness to it and the somewhat believable chemistry between the leads lifts it up.
I guess for a European like myself the pretend country of XY didn't help - we all are familiar with the Greek island with the shipwreck. Overall it can be enjoyable to watch if expectations are kept on the middle of the scale. Although I should mention that this is the only series where I ended up wanting to hear the soundtrack after finishing it.
