I will try to keep this short:

The three main characters are extremely well-written and brilliantly acted. A special shout-out to Oh Jung Se for portraying MST so well and bringing life to the character! The side cast are also perfectly fit to their role and there are seriously 0 complaints in the acting department- the actors deserve all the praise.

The chemistry of the lead couple is amazing, but I would like to add that was sold me was the brilliant chemistry between the brothers. I enjoyed their storyline the most and loved seeing them grow and understand one another.

There are a lot of praises about this drama already and I will add on to say it deserves the praise it gets. However, one major issue not many seem to talk about is how problematic KMY's character is.

I am extremely sorry as this opinion may not be well-received by many but I think it is necessary to share. She seriously had many issues going on and I would have liked to see scenes where she actually receives therapy each time she went to the Hospital for other purposes. Many things she does are unforgivable but are brushed off by MGT as he accepts her personality and Seo Ye Jin plays her role with such charm that the audience does not seem to complain either. She is almost selfish at times as she is only nice to the man she loves and her brother.

In spite of what I mentioned, this show is worth watching for its gorgeous cinematography, the development of all the characters (mostly all), the OST and a well-rounded storyline.
