I just finished watching this drama and all I can say is that it is absolutely amazing. I've watched over 30 kdramas but this is the first one that I'm writing a review for. It's that good.
It's hard to describe why this drama is so good. The plot was completely unexpected, but in a good way. It never left me feeling bored. There are so many plot twists that leave you speechless. But at the same time, it's not too intense to the point of irritating you.
The chemistry between the two couples was so raw and real. But I also loved the wholesome and heartwarming bromance, which was just as entertaining to watch, if not more.
Each and every scene was beautifully filmed. The character's lines beautifully said. The CGI was wonderful and not fake-looking at all. I personally was mesmerised by it. The whole soundrack is a masterpiece too.
If you're looking for a kdrama that will make you smile ear to ear with joy, squeal with happiness, hold your breath with anticipation, and sometimes weep your heart out with sorrow (I cried A LOT), this is the one. The ending is great too so you don't have to worry about being left unsatisfied.
