This show is a masterpiece. That much cannot be denied. It is visually gorgeous, has an amazing soundtrack, fantastic acting, incredible writing, and one of the most realistic portrayal of queer experiences and relationships I have ever seen in a TV show.
The fact that this is not your average 8, 10-minute episodes K-drama is frankly nothing short of a miracle and if this is the level of quality we can expect from Korean film makers if they are given the resources they need to tell the stories they want to tell, then we can only hope and pray that this show is just a forerunner and that there is more to come.

I will admit, however, that this is a melancholy show. It feels gritty and real and just a little bit heartbreaking.
Now, I don't personally enjoy shows like that and I did have some significant trouble getting into this one, not matter how technically excellent it is on every level.
If you are someone like me, someone who prefers a lighter, more humorous approach to serious topics you might also have some difficulties with this. But I truly believe it's worth watching anyway.
Not only do I think this show is something so unique and well-put together that it has to be experienced at least once, it also has a wonderful, fiercely joyful happy ending. I found it so satisfying, in fact, that I was tempted to go and rewatch the entire thing immediately just to experience it all over again.
I promise you this show will not break your heart, at least not without putting it back together again.
Give it a shot, this story is very much worthy of your attention.
