This drama was such a big surprise for me and a happy one for sure!
When I started watching, I didn't really know what to expect. I had read really good reviews and that was the main reason why I started it, also because I knew there was some romance in it and that is typically what I look for in a drama. However, I was really sceptical about it having so many episodes because I do sometimes tend to get bored easily if the storyline isn't very satisfying.
The main point of this drama that really catches and manages to maintain the viewer's interest is the story. It is very well grounded and naturally unfolded, without it being forced or stretched. Actually, it is so well developed that you could very easily believe that it could happen in real life.
However, what I think is the selling point and the best feature of the drama is the acting and the chemistry between the actors. There is not a single one of the cast members that doesn't do a phenomenal job. It was actually my first drama starring Lee Joon and I had no idea he was such a great actor. He does amazing at portraying all kinds of emotions and his on-screen romance with Jung So Min is undeniably good. It is also one of the few dramas that made me fall in love with one of the female leads' character. I am of course referring to the well-loved Hye Young, whose relationship with Jae Hwan is still the most realistic that I have personally seen in a k-drama so far.
That being said, I have to say that at some point I started growing a bit tired of certain parts of the story, mainly the relationship between Jae Hwan's parents and Cheol Soo's dad plot, which for me is only natural after so many episodes. I would have preferred for the drama to shift more of the focus on the main story when nearing its end or, better, for it to have less episodes with less scenes of the aforementioned.
Still, it was so bittersweet for me to reach the end of this drama because I was having so much fun watching it and I can certainly say that I will be rewatching it.
