Ever since this show was announced I was one of the happiest about it and one of those who looked forward to it the most since it is written by Once Again writer, one of my all times favorite weekend dramas.
Then as expected, this show started amazingly.
Everything about it was beautiful until the rom&com were suddenly reduced for the murder plot to gain the biggest attention from the writer.
The show felt ruint and its beauty was lost in a meaningless sub-plot that served for nothing. I thought the writer had great reasons for the mystery / murder plot but it was nothing but a story that took place and ended uselessly.
The final then brought back the beauty of this show that was lost for weeks and made me smile.
This was the show I liked so much, this was the story that I really wanted to watch.
How great would it have been if crash course in romance was a 12 episode drama without the murder sub-plot? I don't think i'll ever stop thinking about the answer to this question.

It was a nice show regardless.
(Still I am bothered by Jaewook and young joo dating and getting married and I do not see this relationship fitting nor appropriate since she was like a family member for him for a long time besides them suddenly sharing something romantic felt so forced and unnecessary but I won't comment on that further.)
