Before I watched this drama I kept reading EVERYWHERE, how the character Song Kang plays was sooo toxic and that he was such a bad boy, and I was really looking forward to see him playing a character like that, well that's not what you will find. He plays a guy with deep emotions but wounded and that doesn't know how to love ( or doesn't really want to) until he actually does and falls in love with Nabi. Not ONE TIME in the show he disrespects or hurts the female lead in any way. He never promised loyalty nor exclusivity and she just has different expectations ( Korean social standards are very much narrow minded when it comes to sex and intimacy in an open way).
I find this show very realistic and aligned with how people actually behave in real life and I enjoyed watching the characters struggling trying to find the way of being okay with their feelings and learning how to express them.
Loved the representation of LGBT relationships and the other secondary couples where adding a lot of warmth to the story.
The only reason why I didn't give it a 10 is because his show would have been priceless with a better script, the potential of passionate and raw dialogues this one has...!!! Instead its a lot of unsaid words and unspoken emotions. But I enjoyed It throughly regardless.
